Just to clarify, I was quoting someone else who referred to "'the male in a lesbian relationship". Just because I really, really resent the idea that one has to be 'the male', or the dominant partner, or the one who does the DIY, or the one who earns the most, or whatever other gender stereotypes you want to sling in. Or that a relationship needs one who is/acts 'male', and one who is/acts 'female'. Or that lesbian relationships need to somehow ape heterosexual ones.................
I know what the original poster probably meant, who maybe thought the word butch was offensive, or maybe just didn't know it? :-)
To be frank, being butch (in terms of not doing traditional femininity) does often get you tagged as looking like a chap, or being mistaken for a chap, no matter how big your boobs are!
Anyway, I'm totally okay with dyke (but some aren't!), butch, bulldyke, lesbian (Oh, but not lezzers, yuck!), even sapphist if you're in a victorian mood :-). But for everyday use, lesbian usually okay -- I personally don't like 'gay woman', because too often, gay gets taken to mean just gay men. And lesbian has more womens history in it than gay.
