Last -- and utterly devastating to your claims -- there are widely available materials that explain how to be attractive to women, but which do not aim at sex as their goal, and these materials do not suffer from the same social stigma (because, as with women's beauty materials, they are about improving the attractor rather than manipulating the attractee).

I must emphasise that "but do not have sex as the goal" is a completely different issue to "they are about improving the attractor rather than manipulating the attractee". Having sex as a goal isn't manipulative. In fact, acknowledging that sex is a goal can make the approach far less manipulative than if a façade of political correctness is maintained but sex is still sought after.
