Is it normal that i find my father sexually attractive? i'm his son after all

Heya, I understand this is definitely a weird one, Considering myself a guy and all. Try not to be to judge worthy ok?

well my current age is over 18, and i live alone with my father. Ever since i was young i found my father to be a protective figure,

He alway's treated me nice and with respect, He has a pure hatered for homosexual guys but upon my coming out, he's slowly adjusted over the years and treats me like a son again.

Ever since i explored and found myself out to be gay, I've always had a fondness, a need to be closer with my dad, I have regular thoughts of being with me, and sometimes have difficulty coming without the thought of him

I've had healthy relationships in the past, usually with older guys as that's what i naturally prefer.

now please note, before you comment. I can't choose like most people who i'm attracted to. its something that just happens. much like people who are attracted to animals or corpses.

I need to know, Is this normal? or am i truly just a strange individual. we don't see my mother much anymore, and they aren't together. What should i do?
is there anything i can do?

Help Me >.<'
