Should I tell my boyfriend I wear a push up bra?

So... I wear the Miraculous bra from Victorias Secret. I'm already a C, so I don't really need it... but I like the cleavage it gives and how comfortable it is. My boyfriend and I have been dating for six months, even though I've been with the bra much longer than that. :P He has seen my boobs before and always talks about how he thinks they're big and stuff. Somehow he hasn't noticed that I wear a push up bra or anything like that. Today our friends and I came across a similar bra adding two cup sizes in the store and he called them "whore bras." He is completely oblivious to the fact that I wear this whore bra. If I told him he would probably make me stop wearing it but I love wearing it. What should I do?
