Thanks, Heidi. I'm not interested in prudish ladies anyway, so I really need to learn to be a little more forward. When I was young, I went out with a co-worker who I had assumed was gay, but the rumor mill had assured me was interested in me. I walked her back to her car and was going to go in for a kiss when I noticed her rainbow flag sticker. I played dumb and asked what it represented. She said it was a gay pride symbol and ummed and uhhed and said "I'm just so proud of my gay friends." So I backed down, but we kept hanging out. Finally a few weeks later, we were at her house during a snow storm and she had to pretty much push me down and kiss me to get things going. That should have taught me to take more chances, but instead I'm always afraid of reading signals wrong, plus I'm now more attracted to women who are very forward.
(As it turned out, I was just her lesbian version of bisexual college experimentation, but we went out about 4 months before it totally fell apart.)
