Gay porn is so much more interesting, usually. What's nice is there seems to be more studios that will focus on the hottest parts of a man with the camera when filming straight or bisexual stuff. I love watching the man's ass, and if he's got an erection inducing backside, I'll put it on pause to admire his butthole, balls, and cock.
I'm also a huge fan of the underside blow job angle, just seeing how far he or she can swallow. If it's a two woman on one man scene, I demand a simultaneous rim job and blow job to be a part of it, or it is a total waste. I could also do without the "bro" 2 on 1 scenes with high fives as the only touching between the dudes. Very, very lame.
