They may not be lesbian.
It just seems more polite to say, "Sorry, I'm lesbian" rather than "Sorry, I don't date jerks".

No, the ones I'm talking about are lesbian.
It's not that I don't meet them again, I'm friend with most of them now.
I'm going to meet this girl again this week, I wouldn't see that happening if she thought I'm a jerk.
Simply it's often difficult to tell if a girl is a lesbian, while it's generally much easier to understand if a girl is already engaged.
