Having Sex because your horny or you just wanna feel close to your partner?

Ok I'm married and have been for going on three years. We married really young. 20 to be exact, just recently I got a second job and hubby works 2 jobs as well. This change has made our schedule somewhat unpredictable and we barely see each other. I'm like craving sex from him and it's not because I'm at all horny it's just wanna feel closer to him. I feel weird saying this. Does anyone else ever have these feelings?
