What method do you all use for finding the right bra size? I know in general a guy has a pretty flat chest. So should I be buying bras that are A or AA and as for the band size, should I base it how women usually measure it? I've got several B cup bras and they don't seem to feel uncomfortable and fit rather well. I just don't like the fact that the cups aren't "filled" because I dislike breast forms. Should I just stuff them with whatever works so they don't lose form? Are there any bras that would fit the male anatomy better? Should I stick with A and AA bras only?

I apologize but I've looked and I haven't not found a thread that answers my questions completely so I'm posting this. Thanks.
