Always need attention

So, long story short. My boyfriend and I have been together for just over a year and I've never felt this way about anyone. He's my one true love. There's just one issue, he's needing attention and constant affection 24-7. I know this isn't necessarily a bad thing, but feeling like I have to do it constantly is getting tiring. It starts arguments almost once a week bc if we are out shopping or getting drinks or whatever, and I'm not touching him or loving on him it's not ok with him. He will say what's wrong why aren't you even showing me any attention. Stuff like that. And I'll be sitting here thinking everything is good and he's thinking why isn't she on me or something? Is this a normal thing? I mean I know guys need affection just as much as women do but why does it have to be forced with him? I'm naturally not the overly affectionate type but I've never had so many complaints about it in a relationship. I feel like im pretty in the middle when  when it comes to showing that stuff . I'm just confused and getting worn out. Anyone else ever gone through something similar?
