"I don't think humans have figured out a functional form of sexual relationships. Traditional gender roles seem useless and non-productive, and these are generally mirrored in sexual roles and representation. Of course, that is true in prostitution as well, but to me it seems fairly rational and straightforward, which is more respectful of the participants than the unconscious charade psychodrama that usually constitutes regular romantic sex."
