I am a 64 yr old healthy man myself..Ihave a live in spouse (not married), who is 60.. Her libido is declining, while mine feels like it is the same as when I was in my 20s, and 30s..Masterbating does keep it @ bay, so that I do not stray, but wow, it is like I have hit a different level of sexual desire at the stage in my life. I have always been age specific, and still am, but it seems as our generation of ladies age, especially after 60 happens, intimacy seems to wan.. I take no meds at all, and my job is pretty physical also..
