For me, the best looking guy out there is Manuel Ferrara, but his style might not suit you or your girlfriend. It's hard to say what your lady will be attracted to, and often performers I wouldn't find attractive on the face of it become attractive due to style/character etc.
In general, though, feature productions usually attempt to hire good looking male performers (and porn in general seems to be catching on...).
I guess it depends what kind of look and style of fucking your girl is attracted to.
