He kept saying "please stop" in the middle of it. That counts as consensual?
Well, yes he said please stop but it depends on whether he is feeling good or not. He looked like he liked it so yeah that's still consensual.
You do know that even if someone does not want to have sex they will still feel good if you sexually stimulate them, right? Consent is not about whether someone feels good or not, it is about whether they want to or not. Get it right.
Well no. Raping someone won't make them feel good if they are afraid. Pleasure comes with lust so how can you feel pleasure if you're drowning in pain? If the rape victim is feeling afraid he'd still feel good? I do have situations where I was forced by my lovers to have sex and believe me when I say even if they stimulate my erogenous spot I felt nothing because I was afraid.
Different from real life, where "No" means "No" (and that's it), in yaoi and mature mangas we get the trope of "stop, not there" while the person is feeling good. I guess it passes an idea of trying to avoid doing dirty things when, at the same time, wanting to do then. Is not harmfull if you don't take out for real behavior with people.
You know that moment I thought it's gonna turn into a rape scene but hell it's consensual it's so good made me relieved. Who wouldn't fall in love with the seme he's so sweet. I bet he's only like taht to Maru lol I want more of them sadly it's completed!
