is One Punch Man a good non-problematic anime/manga with its women characters?

I recently watched OPM's season 1 and obviously amazed with its amazing animation. However, I have heard that apparently the show has a stereotypically "She looks like a minor, but is actually an adult so its ok to sexualize her!" character. I can't stand when media has unrealistic characters, especially unrealistic women because it's in so many pieces of media.
