Uh-oh my dad thinks im gay lol what the heck?

Alright so heres the deal. First of all im not gay. im straight as it gets lol. thing is im 20, i have never once in my life had a girlfriend. Never kissed a girl, never hugged one (at least not a pro longed one like you would in a relationship), never touched one, hardly ever talked to one, and im still a virgin. And even though were both in the same church that btw believes in courting not dating, he still has this thought that im gay and he doesnt talk with me a lot n ignores me most of the time cuz of his dumb umption. What the heck is wrong for having a little respect for women and not wanting to date (whether or not its a standard at my church, i wouldnt date even if i wasnt in church) them because i see relationships, i see all the pain and heartache and i don't want that to happen to me but mostly for me to make a girl feel that way. Whats wrong with waiting till i find someone i want to be with the rest of my life, who i respect, who i love more than any other girl, who i love for her as a person not for looks. Compatibility. Whats wrong with any of that. I veiw relationships as unnecessary and it causes nothing but pain in the end. i am waiting till i find the girl of my dreams. is that so wrong? Just cuz ive never been with a girl doesnt mean ive never been interested in any. How can i convince my dad im not gay? he first asked me that question when i was 13. its bothering me. ive already toled him im straight and i like girls n that ive been interested in them. He refuses to accept that thougth. im confused i dnt get it -_-
