There is love, but no sex...
When you are together for 24 hours, the line is erased, you are always together, there is no separate rest, one wall, one thing.
In sex, the same thing, some poses and places, which is why addiction occurs ...
What is the way out?
Divide the rest, spend time separately and have a little rest from each other.
Change the tactics of sex, as well as postures. There is no way to have sex elsewhere, ok, try sex toys.
You can always find a solution and a way out, the main thing is to really want it!
