At 65, and 64 soon to be 65, I can only attest to how things are with us. She had some issues with dryness, and after several years finally went to a gynecologist, got some hormone patches, to replace the pills that were not working. Once these started working she was more willing to have vaginal sex. I had to start levitra, and after some exprimenting, dividing the pills to smaller amounts, have enjoyed the "help". I have had congested arteries for some time and it makes sense that all my arteries are partially blocked. Levitra just opens things up, and the blood can flow, everywhere. The smaller doses have eliminated the head aches, when the pills start to wear off. I take about 5mg per session, and that works for me.
With the new toys, lubes, and an openess to talk, asking for what you want, sex is, for us, better than it was when we were twenty somethings. Her favorite pet now is the "rabbit", and we have a small herd in the dresser. We have experimented with several different types of sex, that years ago would have seemed kinky......I like kinky today! She likes kinky today! I guess we have evolved to kinky old people. But it is our bedroom, and we make the rules. Sex is all the better for us, but there is a rule for old men, "once a king always a king, but once a knight is enough".
