Am I going to be the first to use the saying "Beauty is in the eye of the beholder"? At the same time, most people are bisexual anyway, so that saying might be more nonsense than not. It has to do with the Soul and Kundalini being raised - the Kundalini is very sexual in Nature, and limiting yourself, if your Natural inclination is not to be restricted, limits types and ways for sexual freedom/union. There is different sexual pleasure to be had with Males and with Females, and then more so with both. Besides, the Male form and Female form are very, very, very, very similar, compared with, say, the Male/Female form and the amoeba form, which look extremely different from each other.
If you mean superficially (your question was vague), in that stereotypical "homosexuality" has to be camp and prissy and stupid, with make-up and glitter and prancing about like a twat wearing certain things, looking androgynous, then that is just nothing but a stereotype which sheeple have been herded into.
