I think it would be fair to say that in fact that the
opposite (of the node title) is true; as
lioncub alluded, not many men are actually attracted to
lesbians per se, and I know of very few
men who look at someone and think that she's a
lesbian and that
she's hot (they'll think she's a lesbian if she looks
butch and usually think she's
attractive if she looks
femme, in which case they have little reason to
assume she's a lesbian unless, say, she's walking down the street with her
partner - and
let's face it, men can be pretty
dense even in situations such at those.)
The
difference is that women are attracted to gay men and men are attracted to women they find
attractive having sex with each other. Women will be turned on by and fall for Real Live Gay Men
(tm), whereas men will
jerk-off to
pornstars licking each other in ways that are quite likely not even
pleasurable; that is not a portrayal of
lesbianism, regardless of the gender attraction of those
performing the act (which, incidentally, in the case of pornstars, quite often identify themselves as
bisexual when asked.)
