I'd call him extremely unlucky, honestly. If they're engaged and can't both enjoy each other's kinks, or at least have sex with each other in a way that's pleasurable to both of them, then they clearly haven't established a good chemistry with one another. As good as she looks, if she can't see he's rather not enjoying things, then she's not worth it. Just my two cents...
It's the age-old issue of lack of communication. Dude needs to talk to the woman about his asks and they need to establish a fair trade of pleasure. Although, it may be a case of him purposefully being closet masochist who won't admit to being dominated by this kinky, cutesy lady. Def would like to se a sequel where they sort their shit out for the better~
