I have been married for 24 years and understand what you’re saying. if you want to spice things up you have to elevate your game, because the usual things now have lost their luster. To be spontaneous is key to keeping it exciting, along with some good play. Go buy a nice lace pair of panties, then take a picture of just the panties not of you in them and text your husband while he’s at work “can’t wait for you to take these off me later” and he will be doing nothing but thinking about you all day. Or give him a handjob in the morning and tell him you want him empty for when he fucks you later. Men like it when women are a little aggressive and make them feel wanted as a man, not just a husband. These little things will definitely make your husband pay more attention and might get your sex life to what it used to be when it was new and fresh.
Often with my friend who is married. Her sexless marriage and mine work well together although she also has a close boyfriend and another old school friend to give her variety!
Went from fucking like rabbits to dead bedroom in a few years. The threshold to get in fucking mood is quite high, involving star alignement, moon, work, collegues, children, rest, time and temperature.
We would go through highs and lows but the highs went well into 25 years plus. Unfortunately she has some health issues physical and mentally that we don’t have sex anymore. But up until the health things were great
so we are similar ages and I too adore my wife as I did when we married 40 years ago. Our relationship has become dominant-submissive and now I love her submission. Creative opportunities keep things spicy and fresh!
