I have to agree, kids these days are really queer-friendly and savvy.

And after all, you're living in sf. Many of their friends probably have gay parents.

Don't make a big deal out of it. Kids don't like that. Also, try to keep your private life private, do a "need to know" kind of thing. If you end up dating multiple people and feel the need to tell them something, actions speak louder than words. My teenage son found out what I was about when I started to introduce him to girlfriends, and then when I left poly-themed books around the house.

This is a touchy subject that warrants no easy answer...My daughter asked me at age 7 if I was gay and she said then that she didn't care if I was. I didn't answer her then, it was if she already knew the answer. Now that she's a teenager and has had the enfluence of her homophobic father, her tolerance is a little different. She will have to come to terms with the fact that her mother and grandmother have female lovers...I missed my opportunity to just come clean. But I keep postive queer folks in her life so she can see that we are no different than anyone else. I'm working on her homophobia by disecting comments and examples of prejudice when I hear it from her or others around her but I keep my dating seperate from parenting because its easier and less stressful for me.
At the end of the day you have to do what you think is best and age appropriate.
