I've seen full girl only lesbians. Most weren't attractive but also far less disgusting than most "oh I totally love girls! (except I date almost all guys) bisexual girls.
Regardless, point is that the idea of girl on girl is hot. While the idea of two guys even kissing makes most dudes get nauseous. Reality doesn't need to equal up for that to work.
