Sex problems

What do you think. I barely have sex with my boyfriend. We been together for a year. In the beginning we used to have sex 2 to 3 times a month. Now that it has been a year we only have sex once a month and sometimes we wouldnt even have sex. Theres no intimacy in the relationship. We cuddle here and there only. I asked him and he said sex gets tiring sometimes for him. He preferred to cuddle instead of making out and etc. Can this become a problem if I don't tell him I have a higher sex drive than him.
