Here's what I think about Christianity and its ideas about sex: they'll hold you back.
I suppose if you only want to use DJ tactics on your wife to keep her happy, they will. But you might have trouble getting a wife in the first place, and if you got a wife as an AFC, it's very possible that she's running you around and wearing the pants in the house.
If I were still Christian, there'd be no way I'd be looking this site, because some of the concepts, like "try before you buy" are completely incompatible with orthodox or even liberal schools of that religion.
One of the problems is that the message it sends is that sex is 'bad', which makes no sense because procreation is necessary, on a species-level. Even in marriage, they make it sound like it's just a matter of curbing filthy urges.
If you're really deep into it, it takes a lot of belief removal before you can get to be a DJ, because religion is a giant AFC-generating machine. It creates submissive people, which is bad for men.
I think though, if you want a realistic view of the way women and men interact, so that you can make better choices, then you'll get a lot if you stick this site and the other seduction sources you'll find on the web. It's the lost art.
