Any straight guy will, if given the choice, avoid scenes of man on man sex as much as possible. They might say it's "just not my thing" out of politeness or tact but watch what they do. When Chapelle said it it was funny because everyone watching can relate and it's a tension reliever to hear what you've been bottling up is actually true. Much comedy works this way.
Interesting concept, that sexual orientation is something we believe is ingrained, but things we find sexually repulsive are fluid and subject to change.
Your reasoning is yours alone and the anecdote can be easily hand-waved away: perhaps you're bisexual or lean more heavily towards homosexuality than most heterosexuals, thus find it less repulsive.
As for not believing in sexual repulsion - is this in regards to gender or in general?
I don't think there's sexual repulsion. Either you are repulsed by something or you are not, whether it's sexual has nothing to do with it. And what we are repulsed by is often conditioned
I think what you're talking about is very different from what my original comments parent talked about, though. Sure, you can have turn-offs. Although what society finds unattractive is also hugely based on culture, just like what it finds attractive.
A small change makes your sentence more truthy: "Many straight guys will".
This isn't just a quibble. Public safety gave up using "gay men" because so many men do not identify as gay but do have sex with men. Thus, MSM is now used instead.
You start with the mental model of sexuality of three seperate and distinct groups - straight, bi, and gay. You then use that mental model to make a statement "any straight guy will avoid". But because your mental model is wrong that statement is also wrong.
You have absolutely nothing to support your statement apart from your own gut feeling.
