That is a very interesting question. I've seen it done enough. I have even done it myself, occasionally donning a female AV to teas a lesbian friend or similar situation. Oddly enough, I am not uncomfortable doing it. I'm actually more comfortable cross-dressing like that then I am using a Macho Male AV. There is no question of my sexuality, and I have no interest in portraying myself as a woman.
I have observed others doing it where there is an obvious change in persona with the change of AV. One person in particular even discusses wishing to become a woman. Interestingly enough he seldom wares sexually provocative AVs and prefers the companionship of women.
