I'll make this short. I am a man (34) with pretty low libido. When I was younger it was maybe higher but certainly never as high as my friends seemed to talk about. I have a gf now (together 6 months) who doesn't complain, but I wish I could be more sexual with her.

About a year or so before her I had another gf and we had sex kind of often (which I also wanted), but we lived in different cities and only saw each other on the weekends so I assume it was part of it.

I honestly can't tell why. I think it might be an age thing, getting lower libido as I get older and partly maybe because I am more relaxed? Hard to say.. Any others with similar experience? Just trying to understand myself better.
