Ok. First off, you really need to find out what she prefers. Some women like strange things. I know several women who enjoy male-on-male anime porn. Others simply like to read hetero smut and imagine. The important thing is to find something you both like. If she doesn't like violence, look for something soft and sensual. If she gets a kick out of whips and bondage, go for some SM. The world of porn is vast and smutiliscious, so you need to narrow your focus and hit her personal "wow, that's sooooo hot" button like a heat seeking missile.
