Yesterday a few hours after having mildly rough sex with my boyfriend, i discovered small blisters around my pubic area. They didn't hurt or irritate me at all and weren't red or anything. I popped a few of them and they hurt just like a blister on your foot would. Also, that region is hot to the touch. I hadn't had sex in almost 3 weeks, and I also kept getting dry and having to stop. Is this herpes? or could this be just from the sex?
