This comment hits me hard. I grow up on a religious environment where sex before marriage is a taboo. Women's chastity is protected and treasured thus only the legal husband who's allowed to have sex with their women. I am pretty open-minded but if you say something careless like that on my place people will assume bad things about you. And then there's me who lives on said enviroment and has been taught that one of women's duty is to get married but still finding the idea of having sex (or being in relationship with anyone for that matter) as absolutely disgusting. My parent will disown me if they know i don't want to get married and have a family

Saldly i understand a bit of what you're saying. I am Italian, so most of the people here is influenced by religious ways of thinking. For example, to have sex without having a relationship is taboo, if someone finds out about it you're considered a whore. And to side with LGBT here... That's another problem but slowly i hope everything will take a nice turn.
Anyway, I decided to try to stop thinking while being influenced that much by those things. Yes for me my first time is important, but I don't think that people trying out with others is a bad thing. Everyone has a different idea about themselves and their sex life, it's just a matter of not judging others as bad or lewd people just because they don't follow your way of thinking.
About your situation, just try to find freedom in what you can. I also find sex pretty disgusting, but I think that one day I will find someone who will make me happy while doing it, and maybe have a family with him/her, who knows.
But if you think that is not your way, try to let your parents understand little by little. I mean, I'm not sure about which gender I like, but I know that if I told my parents that I'm bi or anything that would lead to a huge argument... For me, the best solution is introducing them my way of thinking little by little, maybe you will not change them that much but the could cope with it and not hate you as much as you think they will...
I wish you luck in everything! Don't give up ok? :)
Why is everyone into Masaki? Since there's no backstory of him, he just seems like a guy who bangs any living thing he sees.
And on another note, hope Yuji finds happiness. ╥﹏╥
