I (M) grew up in a home where sex was treated as if it didn't exist. I was was mostly raised by a single mother, who albeit being totally irreligious was likely uncomfortable discussing this stuff with me. Accordingly, sex was never mentioned, all the way through my entire adolescence. I had to "figure out" everything by myself, with the help of Internet, zero input from another person.

During my teen years I was very shy and took pride in being the good child. The convergence of all this is what led my brain to reach the conclusion sex was something wrong, shameful, and embarrassing. I clearly remember I felt distressed upon reading something about sex in an encyclopedia or online for the first time ("this stuff is actually real!") when I was 12 or 13, though I quickly accepted this fact. I'd regularly feel guilty over masturbating, watching porn, lusting, or finding women sexually attractive. The first time I masturbated I felt bad but couldn't pinpoint any concrete actual reason. That shame didn't actually stop me from fantasizing, watching porn, etc, I'd just felt guilty and ashamed afterwards. I once stumbled upon something kinky that turned me on and became worried I'll become a psycho if I keep fantasizing about it.

Over the years, as I grew up and became more emotionally mature I felt less and less ashamed. And sometime after I graduated high school I think I freed myself from shame completely. I stopped feeling bad about porn and masturbate without any guilt for years now. I realized my kinks were perfectly healthy and common after I spent some time reading about BDSM and experiences of other people. I would say I have no qualms about sex.

But I was wondering if this means I genuinely fully embraced sex positivity or there could be a part of me that is still repressed? What signs might indicate that?

I'm asking because I'm trying to track down the cause of an incredibly rare sex-related problem (general primary anorgasmia) I have and I want to see if my upbringing could be the reason.
