i am straight male,
i have questioned whether i was BI before because i think thoughts come to everyone, is a natural occurrence and men just don't admit it. I can find males attractive but i would not want to have sex or do anything with them.
There are stories of pirates of old times becoming gay because there are no women, but when they see a woman, they become straight again. Even dogs or animals try to hump fellow males.
I think its a scary thought for a guy, questioning whether they're gay or not or bi.
I have a gay relative so perhaps its in the genes. Perhaps everyone has it to some degree and it isn't their fault, does that make you gay or not? Maybe its subjective. Theres no real right answer.
I was also sexually abused by a guy though when i was a kid but i think it is not related.
