Is it possible that decades after premarital sex became relatively commonplace, that good sex may be a contributing factor to the marriage in the first place? I know for a fact that I’ve got plans for my girl, and while she can cook, a guy’s gotta do a bit more than eat....
I believe a good marriage provides trust and confidence to really enjoy sex. And it does get better with time. No reason married sex can’t be exciting and something to look forward to, especially after the kids are grown!
