Why do I have diarrhea after protected oral sex?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

I met a guy. I decided not to have sex as I do not know him. He gave me protected oral (blow job) with a condom. Also, I fingered his anus two minutes with vaseline by putting nitrile gloves. That is all and he also sucked my nipples. We did not have anal sex. There was little masturbation before oral. But it has been a week and I am having diarrhea. I am very scared. Do you think I got exposed to HIV (Human Immunodeficiency Virus)? I never did anal sex due to fear of HIV.

Please help.

Hi,

Welcome to icliniq.com.

It is unlikely to acquire HIV without exchange of body fluids. In your case, masturbation and oral sex have very minimal chance for such. Your diarrhea could be due to other infections. I hope this helps.

Thank you.

Patient's Query

Hello,

So can I resume my life, putting my HIV worry behind, or do I need any testing? Please help.

Hi,

Welcome back to icliniq.com.

Oral sex and masturbation are not high-risk exposures. The percentage risk for transmission of HIV is not known in these conditions. Even the WHO (World Health Organization) does not categorize them as risk factors for HIV. Hence the chance of acquiring HIV is unlikely through such modes. However, there are other STDs which have a higher risk of spread through oral sex. As it was a protected one, the chances should be less. But it is advisable to go for a baseline screening and repeat after four weeks for the same. There is no need to panic, it is just a precautionary measure. However, it is advisable to refrain from homosexual activities in future. The investigations to be done are: ELISA (enzyme-linked immunosorbent assay) for HIV. HBsAg (Australia antigen). Anti HCV (hepatitis C virus). VDRL (venereal disease research laboratory test).

I hope this helps. Take care.

Patient's Query

Hello doctor,

I have got HIV ELFA Ag/Ab test and it has come negative.

Hello,

Welcome back to icliniq.com.

It is a good sign. But we need to cover up for the window period and be skeptical about the reports within this duration. As the baseline is negative, a follow-up test at 12 weeks will confirm the result. You can choose the ELISA (Enzyme Linked Immunosorbent Assay) method at 12 weeks or 4 th generation combo test at six weeks to confirm the same. I hope this helps.

Thank you.
