What makes a Bull tick?

I know at a site like this it's probably a silly question, but I'm just really interested in the psychology behind it..

For example, why does a bull love to take a hot wife, as opposed to the seemingly more mainstream man who just wants a single woman?

Strait outa Wikapedia.
Latent homosexuality is an erotic attraction toward members of the same sex that is not consciously experienced or expressed in overt action. This may mean a hidden inclination or potential for interest in homosexual relationships, which is either suppressed or not recognized, and which has not yet been explored, or may never be explored.


Is my guess.
