After breastfeeding, does nipple 'play' bother you?

I know this is a strange topic but I can't be the only one! I used to love my nipples played with during foreplay but after breastfeeding two kids I can't stand to be touched there! Is it due to over stimulation or is it a mental thing, like they're only there to feed now not pleasure. I want to know I'm not the only one cuz none of my girlfriends have the same issue, but then again most of them either didn't nurse or didn't nurse very long. Thanks ladies!
