Would a lesbian allow a guy to clearly hit on her and talk with sexual innuendo in a text / phone game? I've always ended the conversations and said I would call or talk to her later, the response is always some form of "ok." Have been told by some she is a lesbian. And when I asked she said she was a lesbian with X. Maybe it's just me, but I would've figured a lesbian would say something like, "hey, I'm only interested in girls.." or something at the first sign of a guy hitting on her - especially in the phone / text game multiple times.

EDIT: Some of this might become more clear tomorrow. I asked early night time (big bar time here on campus, so I didn't expect a quick response.) and she responded back (drunk) and very late.

The fact she's lesbian doesn't mean she doesn't like lollipops and enjoy being seduced. You just have to know what you need to do. She did give you an IOIs there "I was lesbian with X", she didnt say she doesnt like guys or she's only interested in her.
Keep gaming her, what is the worst case scenario? She turns you down. So what?

Oh, I definitely will. And I have no fear of rejection at this point my life. This whole thing actually pulls me closer to be honest, it feels like even more of a game and challenge.
