Depends what you like... we are put off rather than aroused by gorgeous porn stars with artificially modified bodies looking totally bored by sex, mechanically changing position ever few minutes, and ending with facials. How un-natural!
We both prefer watching real people having non-choreographed sex, preferably with more than two involved. A real favourite of ours is the "Swinger" series shot in La Chambre, with club members having fun. "Swinger 2" actually got us into swinging in the first place; we were watching it one night and after a lot of discussion decided to try the club out. Swinging really was as good as it looked and and the films were totally natural.
Several years ago an American called Candida Royale made porn from the female point of view, lots of seduction, kissing and soft lighting. They were very erotic and totally explicit, but ended with male internal cumming rather than pull-outs. A bit dated now but still worth a look.
