My husband and I have been married for 30 years. We were virgins when we married, and have never been with anyone else.
Sex just gets better all the time!
We are now in our early 50s, overweight, and beset with various physical limitations (me more than my husband) and yet, our sex life is smokin’ hot.
Sex is a skill, like playing the piano, or cooking a dinner, or repairing an engine. The longer you do it, the more your skill improves, and that makes it more pleasurable.
If my husband and I had known back in our first ten years of marriage what we know now about sex, we would have literally died of pleasure while making love.
One of the “problems” we have with our sex life is that we’re so good at it now that it only takes about 20 minutes from start to finish–we wish our liasons could last longer!
I think that women specifically get better at having sex as they get older because they are more aware of what turns them on and brings them to orgasm, and also they learn how to give exquisite pleasure to their husband. And I think men improve also, as they learn to control themselves and wait to ejaculate until their wives are satisfied.
And as wonderful and precious as children and the child-rearing years are, I do think that as the children grow older and less dependent on Mom and Dad and leave home, it’s easier for Mom and Dad to relax in bed without falling asleep from sheer exhaustion the instant the head touches the pillow!
To the OP–one thing I would seriously advise you to do is to not dwell on these thoughts of “will I be satisfied for the next 60 years.” These are unhealthy thoughts, and may lead you away from the wife of your youth. Don’t allow yourself to think these thoughts ever again. Expunge them from your mind, just like the word “divorce” should not exist for you and your wife. I know that you’re just speculating and having a little fun, but don’t do it. This is not the kind of thing you should think about even in jest.
Instead, strive to give yourself to your wife a little bit more every day. From day to day, try to outdo yourself in demonstrating your love for her, and not just in bed. A wise husband learns that sex starts first thing in the morning, continues all day, and achieves its climax later in the day or at night. That’s how long it takes most women to be “ready” for sex–all day!
Something else to always be aware of is that there will be times in your marriage when you may not have sex at all. E.g., if one of you becomes seriously ill, or is injured, or clinically depressed, or if you have a child with a disability, or one or both of you has to work several jobs to make ends meet.
Your love must be strong enough to weather these hard times in your marriage. I am not saying that sex is unimportant–quite the contrary, if you’ve read any of my other posts, you’ll know that I believe sex is what keeps a married couple from becoming just “best pals.” I think sex is extremely important to a marriage–but I also think that there is more to marriage than sex.
Read the first ten chapters or so of the book of Proverbs in the Bible, especially Proverbs 5: 18 b and 19–"…And rejoice in the wife of your youth. As a loving hind and a graceful doe, let her breasts satisfy you at all time, be exhilarated always with her love."
