@3ds1234 Unlike most of the misogynistic morons on this thread I can kinda see where you're coming from. However, I still disagree with most of what you're saying. There is a marked and obvious different between how people treat female "whores/sluts" and male "players", even what they are referred as is drastically different. The terms for females are extremely derogatory, and while you could say that the term "player" also has a slightly negative connotation (many would argue otherwise) it's still far less "severe" of a term. Some people also use the terms "man-whore" "man-slut" or "gigolo", but their usage is almost infinitesimal compared to the previous terms, and it's by no means because men fool around less than women (more often than not, it's the reverse that's true). Casual sex does not make one a "whore".
From my perspective, as long as there is consent between all parties involved, it's fine. I do agree that her forcing herself on him would be very unacceptable in reality, because of the lack of consent, but that is not what my comment was addressing. 80% of the comments don't even mention the fact that yui said no, they are solely concerned with what she blew a dude before, and that she has sex with a lot of different guys. It's not like she finished the act and then just turned around and kissed him. Is there a set time that she should have waited? From the chapter it seems like it's been at least 20 minutes or half an hour. Would it have been fine if she had waited 1 hour? 2? 3? She did wash her mouth out right?
I know people that really have their lives together, guys and girls, who are sex-fiends. I don't think less of them for that. Personally, I would like if my partners didn't have a ton of other partners before me, but that's just my preference, and I know plenty of people that are fine with that not being the case. Regardless, I don't think that you should shun people or say they have a "loose personality" if they like to have a lot of sex. It's a pretty old-fashioned mindset to have, especially nowadays. As long as what other people do isn't hurting anybody directly or even indirectly, I don't believe it's anyone's place to put others down based on their internalized prejudices.
I'd like to stress that I'm not saying all this because you all are insulting a fictional manga character. I don't like white-knighting, and white-knighting for a 2d girl is not what I'm going for, there are so many other hills I'd rather die on. I'm trying to address how incels and neckbeards see women. They have this idealized vision in their minds that they'll fall in love together with a pure maiden and she'll tell them "kyaa, be gentle, it's my first time" and all that crap you read in other manga. The real world doesn't work like that, and neither do women. This mindset is pretty toxic, and if anyone finds themselves thinking these types of things they really need to reevaluate their mentality. Double standards are a real problem in our society, and not only concerning things like this, or only for women. It's one thing to say some stupid things in a manga comments thread, but it's a real issue when it bleeds into real life. Whatever anyone might say, words hurt, and you should try to give everyone a degree of compassion.
