I hear so many people complain or joke that sex disappears after marriage, but that hasn't been the case for me. Our sex life is not the same as when we were dating (we're sober more often, for one thing - haha), but if anything I would say it has gotten better.
DH has always been incredible in bed, and when we were younger I probably would have said it wasn't even possible for the sex to get better, but it has, and it just keeps getting better. Statistically, women claim to have their best sex in their thirties, so I suppose statistically I fit, but I feel like the pop culture stereotype of married sex says the opposite.
We don't have sex every day like we used to (though sometimes we go through stretches where we still do), but we still make time several times a week, and it is incredible. I remember about two months ago after one particularly lively encounter, DH panted that that had to be the best sex EVER, and I'm pretty sure I have that feeling at least once a month! And the last couple days have been mondblowing (several times).
For us, marriage has made it better. How about for you?
