This was exactly my experience. Extreme repression of my sexuality via religion.
Shamed for every impulse. Shamed for masturbation (Not by them of course, they had someone from the church do it. I guess the idea of doing it themselves was just too fucking awkward for them). Shamed for porn (Back when porn was waiting 20 min for an image of tits to load).
It is an overall tenet of my advocacy that this cannot possibly be right. We all hit puberty, all we want to do is fuck as we are driven towards it directly by nature.
Maybe there is a societal need to curate that impulse, I can accept that. But not like this. Not through guilt, shame, and fear.
