Puh, I know 2 mangas with strangulation scenes:

Memento Scarlet
But I don't remember something about the past lover... And Memento Scarlet is far from completed. So they probably don't fit.
Yes! Thank you!
I'm trying to find a manga where the blond guy strangles the black haired guy when they have sex. The blond guy has a past lover who was killed when they were going home from a festival.
I want to read it again because it was shown that they grew old together in the last chapter.
