Hello, I'm 48 and I'm very thankful my freakish sex drive has finally died down. But yes I'm in the same situation. Basically I take Viagra to help. Once wifey starts things, Mr Happy says hello, and things go from there. It works for us. The same advice is often given to women if they aren't in the mood but want to be. Let the man start things, be open to sex, and take it from there. Or try something new to spice things up, talk about your fantasies.
But make sure you get enough sleep and exercise and eat right. That helps too.
Have a serious talk with your gf about how much sex she wants in an ideal situation. Then see if you can meet that or get halfway there.
I have a long time interest in psychology, specializing in relationship dynamics for 30 years.
