Re: Can't sleep after sex
But not consistently. Sometimes yes, sometimes no.
When it's no, it's because she still has something on her mind (not related to our relationship, just the other aspects of life, kids, her extended family, her social group, financial decisions, etc). Sometimes the sex is just a temporary respite from life and as soon as the afterglow dims, all those pesky thoughts come back in.
If she sleeps immediately, and well, afterwords, it's because her mind was already at peace beforehand.
Does your wife tend to overthink things or dwell on external influences?
