Is Your Partner Not That Affectionate?

My husband and I have been together for almost 12 years. Married for almost 10 years. We have 4 kids. 2 boys that are 6 and 8 y/o and 2 girls that are 6 months old. Since the birth of our twins, I've been clingy and wanting affection from my spouse. My spouse hasn't really been much of the affectionate type but now I just crave it and need it. Is it so wrong? It bothers him to some degree because according to him, I want it 24/7. (Which is far from the truth.) He works A LOT. And what little time we do get together, of course I want to make the most of it. We have decided that I'm going back to work soon for day shift. And he will work evening shift. We have talked about doing more things together like going bowling, fishing, movies. Has anyone went through anything like this?
