It is simple communication between partners. Often times I hear how married men don't get sex anymore after a few kids. Ex. They come home from work have dinner and sit on couch till bed time. Wife cleans dinner and picks up and puts kids to bed by herself and then she starts to pick up once again. Then finally husband comes off the couch expecting something. My first thought is how clueless are you? To most woman who have children, nothing is more pleasing then seeing your man tending to his children
For those people without children I would focus more on doing quit acts of kindness for your spouse to show you care. Even change the acts from one thing to another. Ex. I wrote on a bunch of stickies one more for my wife. And each said something I like about her, or something I'm thankful for. Random acts gentleman.
P.s. making her feel good in the bedroom is important but often times how she feels going to the bedroom is more important.
