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.
