Is it normal that i came while grinding?
It's actually happened on three separate occasions, with three different girls. The first time I was in her bedroom, and she got on top of me, and I slid my jeans down a little but I kept my boxers on with my dick against my belly. And so she was grinding on me while I was feeling her up and making out with her, and I felt myself about to come (it's not like I just came out of nowhere, it was a legitimate orgasm, it just came fast) so I just let it happen. I told her, she let me borrow a pair of her boxers, and it was embarrassing, but it didn't faze me really.
The second time, I was just making out with a girl, standing up. It was really intense, and I was rubbing against her and grabbing her ass through under her shorts, and again, I let it happen and I went to the bathroom to clean up afterwards. I didn't tell her. Too embarrassed.
This most recent time, it was like 4 in the morning, and we were making out, and basically the same thing happened from the first time, except this time I didn't tell her.
I wouldn't be worried if this was a one time thing, but I don't think I should be coming in my pants more than once.
