I have run the gauntlet of sexual fun with the wife, over 5 decades. Physical and Life in general, takes tolls on all of us. Thankfully, Im still as horny as a 20 yr old, but satisfaction isn't as often as I would like. Does Anyone have any secrets or know what, if anything interests your granny wife ? I have run out of ideas to keep her involved . Sexual Excitement is Healthy for the Spirit.
For my wife and I (in our early 60's) I have found that once I started focusing on her more that it helped. My wife has a lot of medical issues and isn't always interested in sex. And I found that when she did participate it was more just because she knew I wanted it. So I started researcing how to pleasure women and doing it in front of her. And I asked her what she liked. Initially she would say "I don't know" but then I started asking things like, "do you like it when I rub your nipples? Or when I hit them with my finger nails". And I researched how to find the G spot, and watched videos of where it is and how to best interact with it. Over time she realized that I wanted to pleasure her and that it was important to me. Don't get me wrong, I don't get it as much as I would like, but showing her how important to me her pleasure is that helped a lot. It is a long slow process and probably won't ever be like it was when we were younger, but you hopefully find a happy medium.
I started doing that way back in my 20s. I've always made sure that my GF/wife experienced a couple orgasms before I got mine!!!
