I am always shocked to find anyone in western society has guilt associated with sex, masturbation, any of it. Guilt or regret about being with a particular person, that is a different thing, but guilt about sex itself, it just doesn’t compute for me. I’m sure it exists, I hear people talk about it, but I find it totally foreign.
I once heard a study that married Christians have more sex and more satisfying sex than non-Christians. No idea who or how the study was conducted.
I do know that Christian based shows on TV seem to talk about sex a lot. That whole promise dance wear girls promise their virginity to their dads, or whatever they do, to me is a bazarro, outward, public display of sex talk. I find that very very odd. I am sure it is a minority of Christians who participate in such things. I would think when half those girls have sex by the time they are 17 (I made up that stat, but I bet it isn’t too far off) it comes with some form of guilt, guilt about breaking a promise, guilt about defying Gods command, guilt about doing something secretive from their parents. I’m just guessing.
