Strange! If I had a girlfriend as beautiful, perfect and big chested as you, I wouldn't mind her doing that. End of the day you're still going to be his girlfriend. But I guess that's just my opinion :')
Aww thank you :) But idk he just doesn't want other guys seeing me naked, he should be the only one who see's me naked and stuff, not random guys on the internet. He's a little old fashioned like that and it's cute
