If we aren't talking about genres - like twink or kink - then i would have to say that the thing i like most in porn is chemistry, when the guys obviously enjoy each others company, and the sex. This means that generally speaking Amateur videos are more my sytle because it is usually people are actually into each other, rather than paired up by a studio. Having said that, there is some really hot studio porn out there, and some really talented stars who seem to have the ability to make any of their scenes good.
