I agree. I think the thoughts of the uke while having sex or doing lewd acts plus their personalities also add to the reasons why in some cass people don't complain even when te uke says no to the seme. In Sekaiichi Hatuskoi, for instance, Rtisu is in denial of his feelings, while in Ten Count, Kurose eventually turned out to be correct in his assessment of Shirotani, that is, wanting to be messed up instead of getting cured.

OK, I have to confess, I hate when ukes are screaming "no no no" all the time, it's a HUGE turn off for me XD I mean, if it's at first, it's somewhat understandable (still don't enjoy it very much though), but when sensei has written 3248237 chapters and uke is still screaming "no no no" DA HELL is that? XD Am I the only one who feels like that?

OMG I AGREE! and when the seme actually stop and say "you dong want this?" And the Uke be like " i didnt say stop or i didnt mean it like that" like the fuck u mean then? No means not to do or say something so how the hell is the seme knows what to do?! Like chill and enjoy the sex instead of saying no! Bluidy say yes darn it! That annoys my soul because i dont get why they are saying no lol

I think thats more like a Japanese thing maybe? Most of the normal av videos are the same, the girls always saying "no, its bad, stop" and so on... I think its a huge turn off too, but it seems they like it..

I agree that it is a turn off but I don't think they want it to look forced but the person on the receiving end is supposed to look pure. Like when they'd say "yes! More!" They'd be "dirty" and by saying "no! Stop!" All the time I think it's supposed to have an effect of appearing cute and pure and adorable. (While most people don't think it is I guess that really is a more Japanese thing.)
(This is just my opinion, and nobody has to agree with me.)
In cases like these, especially where BDSM is included, it's almost only a matter of perception to see whether it was consensual or not. Well, firstly, the uke here did not give any verbal consent whatsoever. That been said, not all sex and definitely not all S&M sex has verbal consent. (Yes, there are many Masochistic uke's that very straight-forwardly tell their S's that they love it rough, and they love being spanked, etc.) but not all the time. (This is only based on perception, but after the uke was smacked, he became offended but he started blushing. This is just something that could be considered. That might have been the point where he realised he was being dominated over and his inner M was coming out.)
Take the manga "Ten Count" for example. A very famous yaoi S&M manga. We see our M Uke in Ten Count verbally object the S seme multiple times but the seme doesn't stop. People rarely complain about consent there for some reason. Anyway, the uke there is truly an M, so you literally can't say whether or not the Seme has done a bad thing for not stopping when the uke rejected him, or whether he did good on making his masochistic partner feel good. When our M uke says 'No', it's not always clear whether he's really saying yes or no. Another thing- Sekaiichi Hatsukoi and Junjou Romantica. That's not even categorized as a BDSM yaoi, and yet ALMOST in every sex scene which is ALMOST in every chapter, the Luke verbally rejects the seme. No one argues about consent there, either. Mostly because the sex scenes are still always portrayed in a way that the uke looks like he enjoys the sex anyway, (which he probably does.) But see, that's what makes it hard to tell what is or isn't consensual in yaoi mangas. Although, sometimes it is very obvious when someone is being raped. Especially when that's what the author is trying to portray.
