It is kind of homophobic that people are squicked out by the thought that the person they're having phone/cyber sex with might be
omg a dude!!!1, but in a way that is so deeply entrenched that it's going to be several generations before it changes, at best. But I like the homophobia macro.
I dunno, it seems to me that a lot of guys' ideal is a woman who is hot, but so desperate for attention that she's happy to make out with girls for the benefit of any guys watching, despite that fact that she isn't actually into girls. I don't think that girls in that category use dating sites, though -- they seem to hang out in bars a lot.
