Hi, I've never done anything all my life & then nearly 3 weeks ago around a couple weeks ago I dry humped with my boyfriend. I haven't gotten my period which isn't super uncommon I am usually late or I do miss sometimes, but I was starting to get one every month and I was supposed to get one this week. When we messed around, we did it with panties & boxers. He said he didn't ejaculate and it was just precm, I'm just a little nervous. I don't believe he got anything on me bc I noticed his boxers were a little wet so I kind of stopped it far too early for it to be penetrated on me, but I'd like your opinion
