Why do I like women's bodies but prefer men's gentials?

I don't find men attractive. Period. Since I was a boy and first saw pictures of women it is something I find very appealing. However I don't like open leg pictures because I find v aginas so ugly to look at. It took many years to overcome the repulsed feeling. But for some reason I like to look at diks. I have been to beaches in recent years just so I can see other diks. As I grow older I find myself attracted to tranuals. But I do not consider myself gay. Why do I want my women to have diks or men to look like women?
