The attitude toward feminists depicting them as hairy lesbians is so disappointing. I am a feminist. You don't have to march on the White House and protest to be a feminist. You also don't have to believe that women are better than men. To be a feminist, to me, you simply need to believe that in some way, shape or form, women have or are getting the shaft (no pun intended). For instance, I get irked over the refusal of contraceptive care by some pharmacists (something that to me, a swinger, is very important!).
As for sex-positive feminism? Yeah, there's some dark parts to women's roles in the sex industry. Underage girls being coerced into pornography, the international child sex trade, body dysmorphia, and the like. But we ladies have just as much a role in sex and just as much a right to like it! (There is the issue that women think of sex in terms of how men define it--see faking orgasms, et cetera. I also realize this and keep it in mind when defining my sexuality.)
So I think that a huge part of why I swing is attributed to me exploring my options in a world where it's easier to do so. I can't imagine it's been any easier in the past 100 years to openly have multiple same-sex and opposite-sex partners in a loving, honest relationship without becoming pregnant or sick. I have feminism in part to thank for the acceptance of multiple sexualities, freely available contraceptive and reproductive care, and women as empowered individuals (and in my case, it's in the bedroom! ).
Apologies for my long-winded post. I just wanted to express my thoughts on how feminism and sexual empowerment mesh together. I apologize also if this comes off as too political--in that case, please let me know!
