A friend of mine had the experience of his wife losing interest in sex with him. Turns out she still was interested in sex, just not with him.
I have the complete opposite problem. My GF's libidio is higher than my own and I have a normal drive of a mid 20's guy. The problem with her high libidio is it correspondingly makes her a ultra toucher and hugger the rest of the time. Sit alone on the couch enjoying a movie, no way, she is right there with me wanting to hug or hold me near 24/7. I consider myself a very passionate and romantic guy but sometimes I need my own space.
TBH some times I would just rather watch a movie or lift but I rarely turn her down.
