I don't know how long you have been married, but with my husband and I (we've been married 2 years this Christmas) do flirty things with each other in order to prep for sex. I will be in the kitchen , he will come up behind me, reach for a glass and give my butt a gentle slap. Try being flirty with him, he may respond and become flirty back. Take showers together. Ask for back rubs. My husband loves any chance to touch my breasts. I have come to realize that just like women, men need to know that they are desired by their mates. Try that and see if sex happens more often. Hope it helps.
