early marriage probably is taking its toll on both of you. Well, you should've known in the first place that he's not that affectionate. You should've not jumped into a decision immediately to marry him if you don't know him from head to foot. Now you guys are married and there's no turning back.
The least thing that you could do is to communicate. Sounds very cliche but still holds true in any relationship. Try to talk to him that what he does hurt you. Talk to him that you like him to be this or that but not to the extent of forcing him into doing something he's not willing to do. There are men who are like that, very firm with whatever they are. But if you man truly loves you, then he'll change not just for you, but also for him, and ulitmately for you marriage.
