Some may be offended by the fact that comics are using a lot of sexuality to sell its pages, but I have a different point of view (besides being a man of course).
Comics have grown up in a fantasy where humans, or not, have great skills and stand out over others. Each of the characters represented in comics has something that makes them different but, at the same time, we can relate to them in an intimate way, and so we identified with them.This is where sexuality enters into comics.
We are sexual beings, we have wishes and desires and this is represented in the comics to get us closer to the characters.In the case of female characters it gets even stronger.
As a male, I know that all women are born with a power that, like a mutant ability, remains latent until puberty. Since the powers of women begin to manifest themselves, they can cause many problems and discomfort for them. They begin to wonder at the changes in their body, begin to feel unable to socialize and small problems seem impossible to resolve. But on the other hand, we go through minor changes, just by watching all this. We see them flourish, and out of nothing, we created an irresistible desire to obey them and try to have them.
Women in turn realize this, and in time come to control that power, as a mutant that has a good time at the Xavier Institute for gifted student.Thus, the power of seduction is the most basic special ability of women, and in the case of female heroes in comics, who have spent years learning to use even more special abilities, can use seduction as a weapon of their arsenal, a true power worthy to be represented in the media that is expert in special skills.
