For me sometimes pain as my cervix is kind of fucked. It depends on the orgasm too, clitoral is the best in terms of coming and going but I've had orgasms from being pounded.
Edit:
I forgot to add depending on the dick size it's either feeling deliciously full or being impaled. Size does not matter but any one whose big shouldn't be Jack hammering.
You have to put in effort just to get it and then, you can't even have fun because you need to think of the other person as well and the other person always makes these dumb faces and noises.
Too much work, not worth it, stick to wacking off.
Have you ever waited for something you thought was going to be really cool to come out, sat around and thought about how great it was going to be, and talked to your friends about it, but then when it came out it was only okay?
