I suppose my body is rather short and stout, and I've always been pretty active and beat up my body in a lot of sports and physical activities growing up, so it's not surprising that this carries over into my sex life. I also have a fairly high pain threshhold, so if it's something I really want to do, I don't think about the pain very much. I've also trained myself to not be ticklish (my dad used to tickle me like CRAZY when I was a kid, which taught me how to NOT be ticklish, haha)... ktsp is way more ticklish than I am, actually. We have non-sexual, throw-down wrestling matches with each other often, where we get quite rough and have a lot of fun man/woman-handling each other.
With sex, as long as I'm not on my period, I tend to like it as rough as he can give it... I love taking a good pounding, especially with a lot of force on my thighs or ass. I like being thrown and moved around into various positions. When I'm on my period, that doesn't change, but my cervix can be quite sensitive if he goes too deep... so not quite as much pounding goes on during those few days, unfortunately (and I have to stay in one position, to keep the mess to a minimum). But the slow, smooth, and careful movements can be very hot, as well.
The only other thing that can be a little painful sometimes is when I am not quite wet enough (it takes a long time for me to warm up, more than either of us has patience for, most of the time), and we can't be bothered to grab the lube... so then it can hurt a bit going in. But that lasts for only a couple of seconds, and then I'm fine.
