Well ok, my boyfriend is the sweetest guy, but he gets pissed when he see's other guys looking at my boob's. It isn't like I wear a ton of low-cut shirts either I just have pretty big boob's. I don't know what to tell him is it normal for him to get soooo mad?
He's acting very immature. Childish, if you like. He should be proud that he's got you by HIS side. He should be pleased that you get a little attention like that. It must make you must feel just a little bit special. At least, I hope it does.
I hope he's not mad at you. If he is, maybe he's not the right guy for you. If he's mad at the guys, then he has a problem with insecurity.
Tell him that there is absolutely nothing at all you can do about it. You're a woman therefore you have breasts/bust, and you're unable to unzip them and hide them away! I bet you anything though, that your boyfriend looks/glances at other girls boobs.
Try and Leave any 'Low-cut shirts' home and even if it is just a Guy with a Roving Eye, whenever your Funny Hunny gets 'Soooo Mad,' tell him To.. Be Glad you are Someone Special that he can be Seen with. He is acting Childish and too Possessive, and I am Wondering as I use my own 'Eye' here, dear, if there isn't Something More in Store with this Relationship, where 'Boobs' are not just the Only issue with Your... Boob Boyfriend. God luck. xx
