I agree with you about the timbre of the system. At the same time, IN THE MEANTIME, contraception being available to women is a good and empowering thing. It is providing women with some say in the kind of sexual life they have.
Additionally, your victimization of girls and women in sexual relations is a bit unnerving. Girls and young women like sex, too. It's not JUST a system of constant coercion. Yes, that can be part of it. But it is not the only thing that is going on.
I get frustrated with you throughout, because you rail against the entire system (which I agree is a shotty malfunctioning system) without seeming to want to advocate concrete solutions for the here-and-now realities of people who actually LIVE with the kinds of struggles we're talking about. I don't believe there's any solution for anyone in stopping allowing girls access to the Pill or diaphragms (or etc) just to say, "Hey, guys, why don't YOU take some responsibility." That seems to me to be antithetical to the idea that reproductive self-care can be (and often is) empowering for girls and women. It was empowering for women's sexuality during the sexual revolution, and I would argue that despite the constant pitfalls of our Patriarchal reality, continuing to ensure women's access to control over their reproductive health care is an empowering tool, not a sexist one.
