My SO and I got intimate on Tuesday, we didn't actually have penetrative sex but his penis was all up on my vagina. For some reason it couldn't go in and we didn't do anything because his siblings were up and in the other room. I had given him head earlier but stopped before he came. Today I'm having little cramps (like I normally do a week or two before my period), I feel nauseous and boobs kinda feels weird. I'm freaking out!! I had asked him if there was any pre cum on him before he was rubbing on me, and says I shouldn't be worrying because he doesn't think it's what I think it is. What do you guys think??
