Thanks everyone for your answers! It definitely reassured me.
You know just wanted to experiment sex with men although I'm straight, and I've only dated girls.I had 2 other intercourse with guys before this unsafe one, and I used condoms. With this guy too, but in the action and the excitation, and I felt safe thanks to the T.. So yes I know, it's a mistake. Well, since 3 weeks, I see him regularly and I know he is totally freaked out about the IST things. I know he was tested for that and negative. So the afternoon after the unsafe sex, I did the test for HIV, and some of the IST and I'm all negative too. But I know it was too early, and only testing HIV, syphilis and the hepatitis. Not the other ones.
Gosh, I'll stick to girls now!
Could it be an infection whereas I don't feel any pain? Nor when I pee, nor when I have these discharges, no pain at all, never. And there's no weird smell, it doesn't smell anything actually. But it literally flows sometimes, it's really embarrassing.
I don't really have a GP and I don't know any Dr. here who is "FTM friendly", except for my endocrinologist who is very attentive and responsive by mails so, maybe I'll send her something, see if she can help one way or an other.
I bought an other urinary test that I'll use Wednesday when it'll be exactly 3 weeks after the intercouse.. See if it's still negative. Do you think I need a blood test? It's the same thing right? Checking the HCG thing?
Thanks again, you're very helpful
