My answer might be a little different, but I want to share. I'm 60 and stay horny all the time. I'm on testosterone and that makes things hotter for me, but before I was the same way. Total porn and edging addict. I can hardly shoot cum anymore so that makes constant edging easy and more pleasurable than cumming. If I do try to rub one out I have sensation, but it is very disappointing. So, better off to edge. But, edging means staying horny.
I got over the barrier with anal several years ago when I discovered that obviously what I needed was to get truly opened and stretched a bit. He had 6.5 inches of girth and ruined me the first time he took me. Since then I can't get enough anal. About six months ago during dildo play I discovered penetrating my second hole and that kicked anal pleasure into high gear. Since then I've used my personal dildos nearly every day, save a few days here and there. I've learned how to take a very long dildo balls deep. This still isn't easy and sometimes my hole seemingly says no, but when it doesn't and I penetrate unchartered depths, the pleasure is out of this world. Also at these depths, experiencing some pain mixed with pleasure is simply indescribable.
All in all, I stay horny constantly. Every day is filled with sexual pleasure if it's just rubbing or tugging my cock through my khakis at work over the absolute plethora of hot guys there. I hook up fairly often and every now and then I'll get a chance at multiple hook ups in a day.
So, I'm having some form of sex every day at age 60 and it's hot. I never expected to be this horny and active at 60 but have no complaints.
