You received oral sex and then slept on her bed with your pants on is basically the concern you have, correct? Then you found buildup under your foreskin. Oral sex carries minor risks for std's, very minor. https://www.cdc.gov/std/healthcomm/stdfact-stdriskandoralsex.htm Since you received oral sex, I think really the main concern would be if they had herpes simplex 1, oral herpes. Doubtful. Smegma is actually normal and both men and women get it. It's made from a combination of fatty oils, shed skin cells, and moisture like sweat. It can smell a little. But it's harmless. You've never had it before this? Here's a whole big article on red bumps on the penis. https://www.healthline.com/health/mens-health/red-spot-on-penis#quick-symptom-chart You can always go to a clinic and have them looked at. My guess is this is fairly harmless and you are worrying for nothing. But talk to your doctor.
Thanks for reply..
Yes, That was my concern .. and can std’s transfer in just 5 seconds oral sex ?
Does herpes symptoms stays longer it’s already been more than 2 months?
And which tests are helpful to know what exactly is it ?
Thanks for reply.. I think i am worried too much and that cause so many other thing in body.. once again thanks...
This sounds like balanitis to me, not herpes. A doctor can easily diagnose this. Treatment will depend on whether he/she thinks it's fungal or bacterial in nature.
Herpes symptoms wouldn't last 2 months.
5 seconds isn't really long enough to transmit anything. It's possible, but not likely at all.
