I know this might hurt you, or even scar you, but dare I recommend you to read NTR, particularly Likes NTR Skill web novel? I assure you, the sex scenes and build up is high quality, and if you don't mind with the slight horrific details. You will surely enjoy the corruption and dialogue, alongside the description and almost vivid like descriptions of each sex position being depicted from a voyeur's point of view. There are also side chapters with the heroines point of view of illicit relationships~
I understand you're concern, but fret not, the web novel is on hiatus or incomplete, therefore you will never know whether the protagonist escaped his twisted "skill" or became the pope of "promiscuity", since he was chosen by the Goddess to spread her religion which is lewdness. Also, he's not a beta male, that I assure you, because he is very possessive, and did killed people, because they went beyond the boundaries that allows them to fuck his heroines. Yes, he enables other men or things to fuck his women, but fret not again, because this too is also the work of the Goddess. The "skill" makes him into a "temporary" cuckold and the women he fucks into "unnatural" made sluts. I won't force you to read it, but should you try or at least taste such erotica, I recommend you read this first as a H novel. Oh, lastly, he is not homosexual if you have a problem with that. I bid thee farewell, until fate crosses us again.
Literally just type Likes NTR in the search bar at Novel Updates. It will show the one-and-only best translated NTR web novel there is to read (for me at least).
Not really many - till the translated chapters ntr happened only once, but he got the girl back after he punished her and the guy that did it. As for yaoi tag it's well... true but he did it with a trap and trap's sister, and under influence too boot, so now he just thinks of him as a girl with just one hole.
