Teeny tiny bumps

Tamara

I'm a little new to sex and I've come to realize that I have these tiny, barely noticeable zit-like bumps on the inside of my inner lips. They weren't there months ago, but since I've started having sex, they have appeared. They don't hurt and I'm starting to think they might be from chaffing(?) and being dry due to rubbing against my underwear or something. I'm not sure. Any suggestions? 😅
