Is it normal to let a guy touch your boobs front of everyone!?

at school today a guy I talk to came up fom behind me and hugged me and grabbed my boobs I don't have a problem with it because I like them touched I'll get naked in front of anyone if they will touch my boobs but anyway my friend thinks it weird that I let guys do that and the kid that did that I have slept with he's black and his names Josh i've seen him naked and he's seen me naked so I'm fine with him touched my boobs cause one day In gm when no one was in the locker room (we only have one locker room for girls and guys) I pulled down his pants and grabbed his penis and he took my bra off and had me run around the locker room becuase he wanted to see my boobs bounce without a bra he's sexy and I feel okay with him so what's he big deal.. I think I'm sexy and I know I am so I you wanna see me naked then okayy like pulling my boobs arnt a big deal!
