Hello, I got a full screen sexual health test in November and it was all negative. I haven't been sexually active since April. But recently I started to get a rash on my stomach, under my armpits, groin and bum. I sent it to the doctors and they said it is Molluscum Contagiosum. But it doesn't look like the pictures and it says if in adults it may have been sexually transmitted. But i havent had sex in months and i have taken my tests. I have also taken 5 HIV tests so whats wrong.
