Gay and lesbian seem to be assumed as erotica, while het doesn't have to be. That's what I got out of what they were saying. It was a stupid conversation.
That's just an extremely moronic conclusion to even come to in my opinion. It seems to outright imply that if a relationship isn't heterosexual then it's apparently just completely sexually based which is obviously wrong even if you don't stop and take the time to think about it.

That does seem to be what the quote is implying, yes. Basically a lot of people assume if you're looking for F/F, then you're looking for it as porn.
I wonder just how often they'd be completely wrong about people looking into F/F stuff only for porn. In my case it'd be almost entirely wrong. I generally tend to avoid anything that's completely sex-focused because I far prefer the romance and character development side of things to the sex side of things. (Though of course if the sex side of things isn't forced then it's fine. Ie: Hanjuku Joshi averages a sex scene like every 30ish pages or so which is quite a lot but it completely fits in with the theme of the story and doesn't feel forced or anything despite the frequency.)
