Could I have an STD if I have a rash and pimples on my penis, one day after having unprotected oral sex?

Doctor's Answers 1

One day is pretty quick for the symptoms you’ve described to appear – so I’m going to work with the assumption that this is not the first time you’ve gone for unprotected oral sex.

You have clearly exposed yourself by having unprotected oral sex, so you need to go to an STD clinic ASAP for a screening check-up.

If you had sex with your partner after having unprotected oral sex, she should also be screened.

It’s important that you do so – STDs can be passed on to your partner and baby as well, if they are not treated.

STDs can also cause long term fertility problems, and complications during pregnancy.

In the mean time, you should completely abstain from sex with your partner, to avoid exposing her to a potential STD.

I’d suggest going to the DSC clinic in Singapore, which is the government STD clinic. The good news is that most STDs can be easily treated, as long as they are diagnosed early.

Unprotected oral sex can cause:

  1. Chlamydia
  2. Genital warts
  3. Herpes
  4. Syphilis
  5. Gonorrhoea
  6. Hepatitis
  7. HIV (lower risk)

The risk increases if either you or your partner has cuts around the mouth, bleeding gums, mouth ulcers or gum disease.

Protected sex can still result in transmission of genital warts, which is why it’s extremely common with sex workers and their clients.

I’m unable to make a diagnosis without examining you, but the “pimples” you’ve described may be genital warts, which start of small, and can grow much larger.

Cheers

What could be the cause of a white discharge from my penis?

It could be prostatic fluid as mentioned by Dr Winston, or possible infection with Candida, chlamydia, gonorrhoea or herpes simplex virus. You will need a full STD workup or urine and blood tests to ascertain the cause.

Could an itchy rash be a sign of an STD? (photo)

Hi, I can understand your concern about the rash in view of your exposure history. Certainly, some STDs can cause rash/ skin lesions like Syphilis, Herpes and HIV. Typically, secondary syphilis (that means syphilis that has not been treated and the disease progress to 2nd stage) can cause a rash but the rash is usually not itchy and usually appear as small bumps. Herpes usually cause blister-like skin lesions. HIV rash can vary in appearance and there is no specific characteristic rash that can definitely indicate that it is a HIV rash.
