I don’t think all straight men are bi, but from personal experience and from talking with friends, I would say 9 out of 10 straight men would accept a blowjob from another man if: a) there was nothing expected in return b) there was no risk of getting caught or observed c) there was no risk of the other person identifying them or their family.

That’s a very insightful comment Gts. I class myself as bi because I enjoy sex with men and women. However I am also conscious that I am attracted to women for themselves, whereas my interest in a man is primarily how likely he might be an opportunity for sex. There are lots of celebrity women who I will never meet in person but I am still attracted to them, whereas I have never looked at a male celeb and thought “wow, he’s hot”.

Does this make a true Bi, or just a straight, open-minded guy who likes easy uncomplicated sex? Even I don’t know the answer to that one!

I think that the vast majority of straight men will accept a blow job from another man if there is no chance of getting caught or there being any comeback or complications. I know a couple of gay guys who only like having casual sex with straights because there is no risk of any attachment forming, and one of them likes the idea of being used!
