In my experience if the libido doesn’t atrophy completely it can soon pick up again.

In men at least, regular sex increases testosterone production. I guess it’s a sort of feedback system. You have to want to though.
My regular punting over the years might have been a couple of times a month — I object to paying daft prices. Yet in certain countries abroad it was — and in some places still is to an extent — possible to do two or three a day for peanuts and without anxious wads of hassle. Maybe grab a beer and a sandwich in between. Some Cialis would be good for the first few days but after that the body would just get into a sort of rhythm. I remember doing six one long afternoon/night, just to see if I could. After a week I’d take a break of a day or two. Back home it was back to the old ‘normal’ for a bit.
I think you might come less as you get older and not be quite so alpha male about it all but certainly no reason to throw the jonnies away. They’re no past their sell-by date yet!
