An STD is a disease that spread mainly by sexual contact. A partner with STD may transmit the diseases, causing an organism to the other partner during vaginal, oral or anal sex. STDs are the most commonly spread complicated diseases in the world to catch as you have to be up close and personal to transmit them. What makes these STDs common? The prime reason is mainly that people do not really know how to prevent, treat, and avoid them in the first place. Or when they do, they do not do it effectively.

It is imperative to learn that not all diseases that affect the genitals are STDs and are not always related to sex. Some of these are just sexually-associated, which means that are not transmitted during intercourse, but occur as a result of it. For instance, an urinary tract infection may occur because of the irritation caused by sex.

Below are some of the most common STDs that you should know about:


Chlamydia is a common yet curable STD. It infects the penile urethra in men and the cervix in women. Its most common symptoms are painful sex, skin rash, and discharge from the vagina or penis. Nevertheless, the reason chlamydia is one of the most common STDs is that many people who get it do not show any symptoms for weeks, months or even years.

Despite the lack of symptoms, it is imperative to get yourself and your partner screened if you think you perhaps have been exposed to chlamydia. If left untreated, it may cause a lot of harm to the body in the long-run.


Gonorrhea, which is also known as ‘the clap’, happens to be another bacterial sexually transmitted disease. It usually infects the same organs as chlamydia, and if left untreated, has similar long-term effects.

Gonorrhea symptoms include burning sensation while urinating; men find a yellow, white, or greenish discharge from the penis. As it is with chlamydia, many people do not find any symptoms of gonorrhea. Be aware of the fact that gonorrhea can also infect the throat when transmitted via oral sex and cause a skin rash if it comes in contact with the skin.


Syphilis is another common STD but comes with a notorious history. It is caused by a bacterium Treponema pallidum and could lead to severe complications if left untreated. Syphilis gets transmitted when the individual carrying the bacteria comes directly in contact with their partner, eventually causing syphilis sores that appear on the mouth and external genitals, in the rectum or in the vagina too.

STD Can Lead to Dementia

This indicates that it can be passed on by vaginal, oral or anal sex. In fact, some of the scientists consider that oral sex is mainly responsible for the increase of syphilis transmission in men who have sex with men.


Scabies is a contagious skin disease that is not always sexually transmitted. It is generally caused by the parasite Sarcoptes scabei, where an individual feels itchy skin rash that gets worse at night. These skin rashes are generally found in the folds on the skin, such as on the wrist, between the fingers, ankles, and even in the genital area.

Scabies is contagious and the mite can live for several days off the human body. It not only spreads by close contact, but by skin-to-skin contact, shared towels, clothing, and bedding.


It is one other viral STD and usually has two different forms, HSV1 along with HSV2. HSV1 is generally related to cold sores, whereas HSV2 is associated with genital sores. Nevertheless, it is quite possible to pass on herpes from the genitals to the mouth and vice versa.

Herpes can be treated with an anti-viral medication, but the virus cannot be cured. People suffering from the herpes virus must know that they can easily pass on the virus even when they do not have any prominent sores or other symptoms. Though using a condom can be useful in reducing the risk of catching the herpes transmission, condoms are still not considered to be 100 percent effective as herpes spreads through skin-to-skin contact.


Trichomoniasis is another common STD, and this infection is more common in women compared to men. Some women may consider this infection for bacterial vaginosis or yeast infection as the symptoms are quite similar: skin rash, itching, irritation, painful sex, strong vaginal odor, and frothy discharge.

Men can also catch trichomoniasis, but they do not really tend to have any visible symptoms. Still, being a woman, if you have been diagnosed with the STD, ensure your partner gets treated right away. if your partner is a man, the STD may not affect him much, but you certainly would not want him transmitting it back to you. If your partner is a woman, you perhaps are passing the STD to each other.

Is an STD Rash a Simple Skin Rash? What Do You Need to Know

If you feel any changes in your genital area, it could perhaps be an indication of having an STD, especially when you are sexually active. It certainly makes you more concerned about the different STDs. Be it a small red bump, bruised genitals, or sore skin, it, of course, is no fun at all. On the other hand, most of the times a skin rash found on the genitals area is not always an STD rash. But the point here is how you differentiate that the skin rash you have is not an STD rash.

You must know that HIV rashes on the skin are a lot different than the skin rashes that appear due to diabetes. Therefore, it is vital for you to learn and differentiate between a skin rash and an STD rash.

Irritation, Painful Lesions, Itchiness And Redness

Redness, itchiness, painful lesions and irritation are the most common symptoms of a skin rash that is not caused due to an STI or STD. Severe STD rashes do not cause any pain. For instance, syphilis is a form of a sexually transmitted disease which causes a painless lesion in the genitals. You perhaps would not know that you already have an STD any sooner.  Anything that is serious enough will not show up any symptoms in the early phase.

Symptoms Generally Subside Automatically and Do Not Spread

In most of the cases, STD rashes accompany several other symptoms like rectum pain, pelvic, cold sores, flu, etc. most of the STI/STDs are a viral infection. They do not show any prime symptoms but do spread quickly.

However, in case of an individual having a yeast infection, it creates itchiness, uneasiness, and foul discharge. All these symptoms show up early, are quite apparent and heal quickly.

As it has been mentioned above, the syphilis STD creates rashes on the hands and feet, causes fatigue, hair loss, sore throat, and several other problems as it spreads. Same is the case with chlamydia STD which greatly affects the rectum in both women and men. There are some additional symptoms such as bloody discharge, rectal pain, and painful discharge.

Ingrown Hair

Yeast infection, ingrown hair and bladder infection is generally baffled with genital herpes. Differentiated by bumps and blisters, genital herpes is an STD. if you have noticed mild itchiness and a small cluster of bumps, just wait for a day or two. If it heals quickly and does not spread to a larger area, it perhaps be due to an ingrown hair and not an STD rash.

Genital herpes, on the other hand, comes with various other symptoms such as swollen glands, sore throat, and flue. Besides, the lesions take around a minimum of 3 weeks time to heal. Ingrown hair usually caused when you shave the pubic area or undergo a bikini wax.

Skin Rashes Perhaps Be Due to an Allergic Reaction

In case you have developed dry genitals with too much irritation and itchiness, be certain that it is because of a skin allergic reaction that may be caused by perfumes and soaps. Some individuals perhaps react differently with certain perfumes, dyes, soaps, and detergents.

Oftentimes, the undergarments may also cause allergic reactions. As the genital skin is too delicate, it may react adversely. You may also develop such symptoms quickly. Opting for milder products can be quite beneficial. Make sure not to douche the genitals, or it will aggregate the itching. Prefer switching to milder dry free and fragrant free products.

Heat Rash or Herpes?

Herpes and heat rash are pretty common skin problems. Herpes is a viral infection that is a very common STD that occurs mostly in people who are sexually active. Nevertheless, both bring on different conditions. The heat rash may occur at any part of your body including your private parts, and they clear up quickly. Heat rash subsides on their own from a couple of hours to in merely a day. Simply by washing off your genitals or changing clothes, you may notice the heat rashes subsiding. Try cooling the skin and you will find quite a relief. If not, it perhaps be herpes.

If the redness or itchiness does not seem to reduce after a few days or if the lesions and bumps spread, it is imperative for you to seek a doctor and get proper diagnosis immediately.
