Was I born gay? Or just "daddy issue"

Hello guys I'm 22 years old and I don't usually post something about my problems or talk with someone abou it this is the second time actually I'm lost and I'm not sure about my sexuality okay I don't like women so I supposed to be gay "but" I don't like younger guys too I'm only attracted to guys older than 45 I don't think this is normal I guess it's all about childhood because my dad was a monster a real one and an asshole so I don't think I was porn gay what's happened to me when I was a kid that turned me to like older man only because I'm starving for Love and tenderness so it's daddy issues I'm not happy with this he destroyed my life when i was a child  and I can't live with it anymore I just need a clear answer and I know its psychological problems do I need a doctor or just accept that and let it go
