I used to be the same then I saw Manuel Ferrara and I realized I can only enjoy porn where the performers are enjoying themselves. He may not be everyone's cup of tea, but he fucks like I like to be fucked so, it floats my boat.

That being said, the majority of what I watch is girl/girl and mostly amateur stuff. Sweetheart Video does pretty good stuff and I used to really like Abby Winters before they were bought out.

I identify as straight, but I don't believe human sexuality is black or white, it is a spectrum and some of us are straighter than others and some of us not. I wouldn't turn down sexy times with a lady, but it's not something I'd go looking for either.
