NEVER! My Man and I have been together for over 20 years. We've been through mildly "lean" years, mostly after we had new babies and I was consumed with exhaustion, nursing and infant care. But, it always popped back and the sex was great again. (It was always great, just less frequent when we had babies, maybe 3 times a week instead of 6 to 12 times a week.)
There's no reason for one's sex life to go downhill.
I have no idea if there is a time when most people start to lose interest. I'm not old enough myself to have any experience with that. However, I do notice that if hubby and I haven't done anything for a few days, then we start to lose interest. This means coming back to it even if we don't particularly feel like it to get ourselves back on track. On average, we are about 10-14 times a week. If we haven't made time for each other, we start to get very snippy with each other and feel odd after about 3 days.
If you and your partner are on the same page sexually and in tune with each other it shouldn't. I too have been with my husband 20 years and where it was great way back when it's even better now. The key I think is when you feel it is going that way to try something new and adventurous to get back on track.
At the point when it starts to get neglected and the person does not care to keep it going, fresh and new.
I loved your answer because that is so very true.
Sex only goes down hill because either one or both partners are no longer "there" so to speak. Maybe the "spark" has fizzled or because of daily life obligations like work, family etc they have neglected to make time for each other so there is now an emotional disconnect of sorts. Or maybe it is daily stress that is getting to them and lowering their sexual desires.
I think if you keep it fresh and try new things it doesn't have to go down hill. There are nights that I'm tired but I try to find new things or sexy outfits and we usually do it 6 times a week and we have been together over 7 years and I work about 50 hours a week
At what time in someone's life does their sexuality start going downhill?
When the spouse would rather cuddle up with the dog than you; when your spouse would rather watch Stargate with headphones on when it's time for bed; when your spouse puts headphones on after the kids have fallen asleep.
When my partner tents to show no interest, runs around and become in toxic! The relationship has no flames to ignite spontaneous moments. I'm dangerous and promiscuous, have high sex drive! Strap me up on top of the hood of Pontiac G6, someone watching us get off. Pick me up, slam me against the door and thrust me!
Other people have talked about their relationships, and those can go bad at any time, from a week in to 30 years or more in. A relationship is a lot like a garden: you have to keep pulling the weeds, and watering/feeding if you want it to grow. And that care is required as long as the relationship exists.
But your partner is only half of the equation, at most. You also have to take care of YOU. At any time of life, but especially once you hit your 40s, staying active and healthy is VITAL to having a good sex life. I learned this a couple of years ago after a sports injury kept me from exercising for a few months. I found my sex drive plummeted and only came back after I started exercising regularly again. I've also found my libido drops off if I overeat, or eat unhealthy foods. The "garden of the self" has to be tended, too.
