ManofFaith, I think that you can learn to exercise some moderations with this and that, eventually, you'll find you're comfortable with what you're doing and balancing that with your faith.
Part of the issue, I think, is that a lot of your evangelical/conservative types (Southern Baptists, for example) as well as devout Catholic types frown on any sort of sex that's not for procreation purposes. I get the feeling from some people that sex isn't supposed to be enjoyable. I've also been told point blank by some people that, because we're not having kids, we shouldn't be married. Some people have a way of attaching a whole lot of guilt to sex, and, frankly, I think that's a shame. I honestly do think God intended us to enjoy sex. And, just as He wired us all differently in terms of what foods we like, what our gifts and talents are, and what we look like, I think maybe we're all wired a little differently in terms of how we like to enjoy sex.
Look, it's not like you're talking about making your wife your 24/7 sub, right? You're not going to forget your vows, you've established limits for yourself in terms of not looking at certain things. I've done the same thing. I had a long talk with my husband about what is acceptable behavior from me on this forum. I may be tempted on occasion, but faith isn't true faith unless you work at it, right? It's not something you just pick up along the way and carry with you. You have to work at it.
