Are you looking for fisting, pissing, and whipping?
You will find that in some Titan movies, most notably the Fallen Angel series.
Raging Stallion also puts out a lot of fisting stuff.

Or just rough sex in general?
I've heard of some straight movies where guys stick woman's heads in the toilet while they fuck them, and other rough things like that... I don't know of any studios that do rough stuff like that. I guess there are some S&M films you can get from Zeus studios and the like, but from what I hear, they don't have a lot of sex in them.

If you are looking for no-condom extreme sex, then you might want to check out DickWadd studios.
