I've said it before on this site actually, and I'll say it again. I like to go commando. I'm not a woman's libber or anything, I just prefer not to be constricted. But if I were boobless, I could definitely go braless. But breasts often become distractions at inopportune times.
Breasts know no symmetry.
So that's my answer. And yes, this would probably not go over well with the boys. But hey, that's their problem. If I had to have one body part removed, I'd choose my thyroid. Although it would diminish my capability of a normal life, I would be able to function normally with medication.
