Maybe he is bisexual at the very least, and just wants a smorgasbord of titty and dick at the same time (on the same person) for convenience. However, if he has absolutely no attraction to real women with God-given vaginas, then he is not bisexual; he is gay.
Some men will go through mental gymnastics in an attempt to deny being called gay, so they try to deflect from their their love of dick by messing with effeminate men who dress up in wigs, makeup, etc., so they can lie to themselves, and pretend that they are with a woman.
