Honestly

As the uke has a history with cheating, I can't even blame the seme for getting mad in this context. I do wish they just talked it out though, and that he didn't resort to forcing the uke. His worry is obviously valid, but doing that isn't. Authors always include scenes like that in order to draw sexy times while there's conflict, but it doesn't feel sexy to me at all. It's a huge turn off, if anything.

Talking about their feelings, though, now that's a turn on
