My co-workers don't know my sexuality...?

[hotttlikeeefirrrrrre]

Well i've become friends with some of my co-workers they all talk about their husbands and boyfriends. They ask me do I have a boyfriend I say no... but they don't know i'm lesbian. Then they say they're going to "hook" me up. But I don't know whether I should let them know i'm lesbian ....what do I say?
