Is it normal i think i might be gay?

I have dated a lot of people of the other sex and can be very charming when need be. Im an expert at flirting and have helped a number of people of different sex score thier desired mate. So essentially know how to charm both sexes. Men overall run off ego while women tend to run on esteem and vanity. Tell a girl shes a buetiful angel, tell a man hes amazing and compliment his attitude and ability. Now some see through this facade but doesn't mean it isnt true most of the time. When in highschool ive had very little attraction to either sex. I didn't find anyone physically attractive. forced myself to date the other sex as to aviod persecution but often never liked my partners. I had a few crushes in my life but it was never based on looks. It was more I loved thier personalities or qualities and these people have been of both female and male sex. This frustrates me.
