Try and stick with companies like Vivid, they seem to have more of what chicks like. Stay away from things like Max Hardcore, or Red Light District...she might never let you fuck her again, if you bring that stuff home. It's good, but not for most woman. Another thing
You Might try, is amateur movies. Sometimes the gf's/wives like it better, when it's just another girl like her, and not a pro that has had plastic surgery, and a professional make-up artist and light crew to make her look spectacular.
