Do straight men have guy crushes/fantasies?

Almost every straight woman I know – including myself – has girl crushes. despite being 100% certain that I am straight I even have the odd lesbian fantasy once in a blue moon, I’ve definitely thought about experimenting just out of curiosity. I’d always pick men to be with therefore I don’t consider myself to be bi at all.
Does it work the same for men? i know its more taboo for them to admit to thats why they never talk about it openly but do straight men ever get curious/tempted about another men? have they ever have a gay wet dream? Do they have guy crushes??
