Desiring to have sex by both genders is a natural thing. But showing/needing affection is as equally important. Some men, including myself, really crave kissing, hugging, cuddling, saying nice things to one another just as much as sex itself. Sex is a good thing but it's not on the top of the list of things showing if a man wants you or not. I would be much more worried if he avoided affection and any other kind of intimate interaction of the sort. How much sex do you have a week with him?
