Put it to you this way: any guy who is attracted to you because your bra is padded will also be the guy who complains about it being "deceiving."
But for the rest, I wouldn't really call it "deceiving". It's not like when the bra comes off, he's there with a tape measure, verifying his estimates (and if that is his response, I recommend the bra goes back on). If it makes you comfortable, or helps your clothes fit better, then go for it and don't worry about it.
I have had guy friends that really hate it. Some just don't care. It really is just up to the kinda guy you're around. If it is like 2 inches thick, they will probably get on to you about being fake, something ALL guys i have met hate. But something a little comforting, not all that bad, and makes you walk around with some self confidence and a pep in your step... I am sure that when it gets down to the nitty gritty, they don't care really.
As long as the padding doesn't exaggerate TOO much, most of us wouldn't be bothered with it - unless the man happens to be a superficial turd.
We assume many women wear padded bras anyway.
*wear padded bras
Sweet mercy. Are there really people out there who get "where" and "wear" mixed up?? I guess the answer is "yes". Sad.
