[Question #4394] Oral Sex Exposure

28 months ago
Hello - I am a male and received oral sex from a male last night. Immediately following, I noticed some small dark red spots on my penis tip and near opening. They were not there before for sure. Would an std show up that soon? It's been almost 48 hrs and they are still there. Could this just be a blood blister or some kind of skin reaction not related to an std? Herpes? He said he was just tested in September and was clean. Please help

Welcome back to the forum.

One of the main themes on this forum -- which may have come up in your series of threads 15-20 months ago (I didn't read them in detail) -- is that oral sex is safe sex. It's not completely risk free, but the chance of infection is low for all STDs and virtually zero risk for some. The chance of infection is far lower than for vaginal or anal sex.

No STD, and no infection of any kind, can start to cause symptoms immediately. It always takes 1-2 days, minimum. Physical trauma (e.g. strong sucking, resulting in broken blood vessels) could explain something like this. If it looks like a "blood blister" that's probably what it is. And there are no STDs that appear like this. If you remain concerned and the spots don't clear up in the next 2-3 days, see a doctor or clinic. But there is no chance this is an STD from the exposure you have described.

I hope this information is helpful. Let me know if anything isn't clear.
