So I recently found this subreddit and it's intrigued me. I'm in my late 20's early 30's been married for over 3 years now. How can I apply these principals to marriage if at all? Also links to more info about this life style would be appreciated especially as it applies to being married.

Edit: We've known each other since before high school but began dating during college. She comes from a strict Conservative Catholic family and was very very reserved about sex when we got together. We have no children yet but both have agreed we would like to. Currently we disagree about when, I'm ready to have kids now but she wants to wait another year because of her career.

Sex life is below average I would say. We only have sex when I innate it. I can count on one hand the number of times she's initiated sex during our almost 8 year relationship. She says mostly because she just doesn't think about it. Right now I'm getting to the point where I don't care about having sex either because I'm tired of always being the one to get things started. My wife is pretty hot and not just by my standards either I'd put her at about a 7 or 8. We both workout together regularly (Crossfit) and eat pretty healthy too.
