I think many straight men, including me, have had a fear about being gay or bisexual, especially when young, due to what society taught us. You'll know more than me but I think every males is bisexual to some degree.
I recently met an old friend, after 30 years. He came out 29 years ago, aged 28 and it was interesting hearing his story. Also sad, he went through a lot, not wanting to come out as he was ashamed and scared of what his friends would say. He was a guy who was incredibly good looking and got all the girls. Lovely to rekindle that friendship.
I think differently about LGBQT to gay. I don't think they should be lumped together.
