I think this is HOCD?

I think this is HOCD but not sure I was drunk one night and I had a thought of hugging and kissing him on the cheek and saying happy birthday(it was his birthday) then came the unwelcome sexual thoughts and questioning and doubting my sexuality (this has never happened to me til now) I've always liked girls and still do and then came "what ifs" what if I'm gay what if I'm coming out but girls still arouse me and erect so I figured out that's impossible then I thought the "what ifs" again what if I'm bi what if I went to my doctor and she said I have generalized anxiety so I started to do some exposure stuff watching videos and nothing no arousal no erection just a sick feeling in my gutt and weird pain in my groin not a good feeling and makes me sick also everytime a guy walks past something in head says look at him I'm not happy I'm miserable alwaysxworrying about this I'm not homophobic I know people who are and if this offends you I'm sorry tell me is this Hocd or Pure O
