Most people have found themselves attracted to someone of both sexes at some point.

saying "most people" is a very bold statement. You have some evidence to back that up?

many men admit that though they consider themselves "straight," they have found some obscenely attractive male star at least slightly (and usually uncomfortably) arousing.

never met or hear of a man who admits that. You have some evidence of that?

Many women also admit to finding some celebrity women attractive.

how about some evidence of that?

Honestly, I'm going to need to see some evidence to believe any of that, because my experience has not led me to such a conclusion. But your statements are bold and phrased as if factual, so I'm sure you'll have plenty of evidence to offer.
