He won’t share things with me ?

So my boyfriend is really weird about sharing things with me .

He’s weird about sharing straws and utensils with me , we went to get ramen and I couldn’t finish mine so I offered it to him and he accepted it and said “ wait let’s switch these “ and switched my utensils with his ? And I’m like wtf you know I ate with those chopsticks and it’s touched the soup also wtf this man literally makes out with me and eats me out why the hell is he so weird about sharing a pair of chop sticks ... and when we go to the movies he doesn’t want to share a drink even though we always get a large one he wants 2 separate straws ... and I’m just confused I let him be but I’m confused as hell as to how you can eat someone out but not wanna share a straw w them
