I had sex last night and when i awoke this morning i had a big purple bruise on my penis. I think it was the condom that caused it but i'm not sure, has anyone else ever had this?
Bruise on penis
I doubt it had anything to do with the condom.
Most likely during sex you rubbed the penis a bit too hard or got hit against the pelvis of your partner causing the bruise. The pelvis can also cause small cuts on the penis as well.
It's all normal, sometimes you just have to find other positions/angles for things to me more comfortable.
