Not that I am a man, but I know that many men, even some gay men, who take huge pride in their manliness and are very fixed on what a man is supposed to be. Men kill the spiders, men are the fixer-uppers, men bbq, etc. Experimenting with other men doesn't normally come up on the manly to-do list.

But there is nothing set and stone when it comes to sexuality. There is more to sexuality than just sex. Maybe it's not men you are attracted to. Maybe it's just the penis itself. There are male submissives who are 100% straight but will enjoy being dominated by a woman wearing a strap on. On the other hand, there are 100% straight men who are completely comfortable with letting a man jerk them off. There are straight men who are compltely comfortable with wearing women's underwear. There are some men who take so much pride in their manliness that they won't have anything to do with letting women be in control. It's just finding out what you are comfortable with doing. You might not be comfortable with hookups, you might need someone you are close to who will let you indulge in these fantasies. If you want to stick with women, maybe try having the women use a strap on (obviously, take consideration into with who and how you bring that up in conversation.)

You can always email me if you want, another user introduced me to a website that I think would be helpful for you.
