For most, in my experience. You have to be careful with each thrust or you'll hit her cervix. I had a partner once that actually liked it when I would hit her cervix. Actually asked me to do it. At first I thought she was just being super accommodating because she liked me. Then she kept insisting I do it. Blew my mind that I actually found a girl who wanted that.

Dude, my wife had a copper birth control implant (IUD). Had to have it removed after the day that thing stabbed me in the foreskin. I’ll never forget that pain. Took me months to get over the fear and be able to thrust recklessly like the good ole days.
