I have been dealing with the same problem for many years and I still have no idea who I am.
My main issue is that, I'm not fully against dating another male, but I wouldn't engage in sexual activity with them. This isn't really a problem, but I'm not against engaging in sexual activity with a female. I never really thought about who exactly the person I feel in love with would be. I never saw a problem with them being female, male, ore even transsexual. Love doesn't know gender in my mind, but I still would have preferred a woman for some reason. I don't know if this is pressures from society, or that I'm just trying to be someone that I'm not, or if I'm just really confused. I don't know. I guess most of the confusion comes from the fact that I feel romantically pansexual, yet I feel sexually heterosexual, or asexual/demisexual, I'm still not sure about that. :I
But since I'm with a female that I'm commuted to, I guess it doesn't really matter. .-.
