Gutsygirl, I get the lesbian reaction too. It doesn't really bother me but since I'm not gay it's wasted effort for everyone involved. Though I've never had anyone get really pushy with me yet--but aggressive guys hitting on me make me nervous too.
I definitely need to make sure I get enough sleep without some bangs to hide behind, and eating well has become a bigger priority for me since going sly.
"Mainstream" society seems to have 2 major explanations for girls going sly:
1. Illness/supporting a friend/charity w/ an illness
2. Homosexuality
There's also a vein of "rebel going thru a phase" which, with my piercings, I'm surprised I haven't heard yet. I dress pretty boringly tho so maybe that's why.
None of these are negative in and of themselves (well, some people delivering the stereotypes can make them pretty negative) but it's annoying when it's just simply not true.
I think the social reaction to slyettes is changing, though, and quite quickly. We're a little behind the guys in terms of universal acceptance but we'll catch up!

Last week when I was feeling a little insecure my therapist assigned me to count all the sly/closely buzzed women I passed in the street. It was a very normalizing exercise but I do live in a city where the deck is stacked in my favor in terms of diversity
