It’s certainly not what you would discuss with your mates down the pub on a Saturday night. But I am very aware that in reality it’s a lot more common than most str8 men would care to admit.
For most str8 men it’s something they think of while masturbating, or having sex. It remains a very private fantasy. Others will experiment, they will occasionally feel a real need to have physical contact with another man, or simply to touch another man and his cock. Some men are very disturbed by this tiny part of their sexuality and it becomes a very big issue for them. These men often become very loud, very homophobic. So the next time you hear some guy shouting about “queers” and all that, don’t be too harsh on him just smile and politely tell him you understand what his problem is.
