Good points, Nathan!
On the subject of 14yo's having sex - - of course people are sexually active at that age! My best friend in high school lost his virginity at 15, for example. All I'm saying is that, hey, if someone is uncomfortable with the subject matter of teenage sex, that's fine by me and I am happy to brainstorm how to work around or work with that discomfort.
Now, just for argument's sake, if someone said they were uncomfortable with gay sex, I would tolerate their sex-squeamishness but try to explore their LGBT-squeamishness. A recent session of Hot Guys Making Out really brought out some underlying homophobia in the game group (thankfully, no one who had seemed like an ally was proven to be otherwise), and I think it's important to address these things head-on.
On the subject of characterization of women, I think you raise some important criticisms. I'm not interested in exploring archetypes that deprotagonize or diminish women, and it's definitely possible that this idea could be taken in that direction if the point had not been raised.
None of the "feminine" playbooks in AW are degrading, objectifying, or minimizing in any way; on that note, there are few strictly-gendered playbooks (especially in the core set). Instead, there are playbooks that give the "concealed" option, and those that do not. Those that do not, however, tend to still have a plethora of options: "man, woman, ambiguous, or transgressing." Lots of room for expression, which rocks!
One my players in a current AW game actually chose "concealed" and corrects anyone who uses gendered pronouns for hir; it's been a neat, organic opportunity to teach folks about gender-neutral pronouns like zhe and hir.
