me and my boyfriend were playing around with eachother and we started masturbating eachother he did it really hard to me and has been doing it alot latley. Can this be a cause to me feeling really sick to my stomach latley ?
No not at all, but you should tell him to do it a little more gentle, and slower. Tell him it's not that it doesn't feel good, but you just wanna try it. And he won't feel so bad.
