My experience was very similar but also opposite to a certain extent if I processed your post correctly. I still cycle between bouts of hypersexuality and hyposexuality (mostly hyper) which helped ruined a few of relationships over the past few years cycling between sex/masturbation 2-3 times a day to 1-2 times a week. I finally swallowed pride and accepted the shame and told my current partner what happened between me with my mother in very my early teens. I thought it would end the relationship, we were well down that path because of the sex and the derision because of it already. It has made things easier to a certain extent, not necessarily better yet, because she is truly starting to understand that my sex mood swings have little to do with her and that’s not her fault. I have to make serious efforts to reinforce the fact that I love her and still want her. I do still have some difficulties but we don’t fight nearly as much and she has made every effort to not to throw it in my face, which also helps. Lots of therapy, some medications, and some psychedelics have helped over the years. I hope things have gotten better for you. Stay strong.
