My H and I were 25 when we M and we both got along with each other's friends just great. Doesn't tell you much. Sex drive is often just biological. You can WORK at it til the cows come home but I'm more and more convinced it is not something that usually improves with just more effort. It's either there or it isn't. Sorry, but look at all the cases on this board that have not made much of an improvement after YEARS of trying. And we LOVE our spouse. That is not the issue. It's just very complicated. Sorry.
