Since feminism, women are more sexually empowered, have access to contraception, are free to have sex before marriage...so I don't see why feminism equals less sex? I think feminists are having more sex with more partners.
Unless she means the brand of feminism that says no to rape and forced marriage. Because I can see why some men would be put out by those feminists demanding criminal action on rape and forced marriage. And feel they can't "get" enough sex because of those restrictions. Maybe replacing those victims with trafficked women could help those guys?
Depends on whether sex is something two people consent to, or a man forces on a woman really.
