Sex will definitely change after marriage. The main issue is that sex sometimes lacks priority – especially when there are children in the house.
Putting aside the question of frequency, a couple must agree to honor and set time aside for connecting sexually. Sex is not something that is done, rather it’s a place that you go. Men must understand that women must have an arousal period of time to transition from the work a day mom role into that of a sexual being. This transition begins with touch – simple stroking. Women sometimes complain that any touch has to lead to sex. This does not have to be. If your husband understands that despite a turn down that you still see sex as important – it will be easier to cope with.
