No.
Hopefully you already know that this is normal; no pair of breasts is perfectly symmetrical. Most guys won't notice because the difference is typically imperceptible. Even if it is noticeable, most guys won't care. Incongruity doesn't take away from the enjoyment factor. Unless of course you are dating a moron who notices and objects. If that happens, ask him if his balls are exactly the same size, and when he bends over to look, kick him out the door.
One caution: if either breast has changed size significantly over a short period of time, you should have it checked. That is not normal and could suggest a more serious problem.
Otherwise, fuhgeddaboutit. Guys like boobs. We don't care if they're not perfect. What's perfect, anyway?
Thanks for the question.
Would you care if one nut was bigger than the other?
BAWHAHAHA, 'when he bends over to check kick him out the door', All the guys I've been with have had uneven nuts, except for the present one, and his wang is a little bendy, no I didn't / dont care, (and yes there have been more than 5, hahaha) Its funny what women worry about.
"Its funny what women worry about."
Indeed.
Actually, this is really reassuring. Assuming, like I am, that you're being honest. Those little imperfections get at women, and we tend to over think every flaw about ourselves. Glad to know men aren't as insensitive as we thought! ;)
I'm not lying.
My girlfirneds boobs are noticable different. Not like way off or anything, but you can see the difference. She's self concious about it, but I can't express to her how little I care.
You'd have to be really shallow to care about something like that.
