I’m in the same boat, just a little further out to sea.

FWIW-
I’m 50ish, and went to the urologist about some orgasm issues and low libido. Found out it was common in men my age. So I was prescribed a daily med. This has elevated my ease to be aroused back to the way it was when I was in my teens. I should have gone years ago.

Also-
I’ve been married 30+years and love my wife, but she has always been controlling and manipulative. I was the giver and she the taker. I awoke from my situation when I quite accidentally met, then fell in love with and eventually had an affair with a young lady half my age that has lasted 4 years. It was liberating and made me realize how wonderful loving relationships can be. With her I had emotional first and sexual fulfillment second. Sadly, we are parting ways amicably. I find that I do not have any fulfillment emotionally with my wife and sex is boring.

I have just recently thought about exploring sexual activities I would have never considered in the past. I may be in some sort of midlife crisis, but I don’t want have regrets.
