My boyfriend crushes me when sleeping?

Ok so my boyfriend is a big boy and when we sleep he loves to wrap his arms around my ribs and waist. Now this is problematic because his arm puts a lot of pressure on my ribs and I struggle to breathe in my sleep.

I haven’t told him and I just soldered on because I was afraid to hurt his feelings (He’s got self confidence issues)

But if we continue to sleep together I want to be able to breathe properly.

How do I approach this subject without putting him down unintentionally?
