What would you say the contributing factor(s) are to yall sexing so much after being together so long?
1) I'm big on health and fitness.The first sign of her falling off, I call her out on it. I eat her food when we go out so she doesn't get fat

. Order water, take the stairs, park farther, etc. Neither one in the relationship should ever let themselves go. I bust my ass to look this good, so should she.
There's also been studies on exercise. Women get some sort of high/arousal at the end of their work and of course men get higher testosterone. Plus, if you look good, you feel good
2) People change, even in a span of year or two. Couples have to grow together and if they don't, it's going to be a problem. Sometimes couples stay in relationships too long and end it too late

It might sound corny but we love each other, so it's not just a physical connection but a mental one too.
If those two notes are connecting, I don't see why sex would be a problem unless they have kids.
