I am wanting some physical affection from my boyfriend.
Why do you want some physical affection?
Because I get lonely if I don't get any affection from my boyfriend.
I can understand how you are feeling about this. Not everyone enjoys physical contact, so you should respect their personal space. I would let him know how you are feeling and it may be that he just doesn't think it is a big deal as you would.
Aww, I just want some cuddles. How is that a bad thing? I'm crying over here.
I can understand your need for affection, but not everyone is good with physical contact so you should respect that. Maybe you and your boyfriend can compromise on the issue. I would talk to him about it because he might not think about it.
