Should i not be telling him this?

my boyfriend is one of those extra manly macho dudes who is always showing how hes dominant and possessive over me which i find very attractive. like hes a really good boyfriend. he treats me like a trophy :) anyways, it seems like literally ALL OF HIS FRIENDS WANT ME. like they always call me text me facebook me. all of them proposition me for things. and im thinking these are supposed to be his closest friends?! now i always tell him everytime it happens, but its becoming more and more frequent. not only am i dealing with his friends im dealing with other men too. i feel like maybe i shouldnt be telling him every time someone does something to me. but i want to keep the relationship open honest and trusting. we do love eachother. i just dont want him waking up one day to realize that he cant deal with all the other male attention i get. HELP!
