Agree with the others that I don't see why it matters and its frankly pretty offensive. What if you've never been with a man by choice but were raped, does THAT make you somehow less of a lesbian?

I know the LGBT community can be so much judgemental than it should be about so many things (like dear gosh I can't tell you how many times I have been completely ignored in a bar or the LGBT community center or even friggin pride because I don't "look like a lesbian" or even had people openly express complete surprise in those kinds of environments to hear I'm gay. And then oh to be a femme who is generally into other femme women, apparently that's not supposed to happen either...) but gosh, how is it we are begging for equality if we judge on so many insane stupid levels about gender expression, attraction, who we've slept with or loved? Why is it okay for LGBT folks to judge other LGBT folks but if a hetero person judges one of us for the same darn things that's discrimination?

The fact that one of your previous partners was a Trans woman is nobodies business but yours and hers.
