I can't stand any, absolutely ANY activity near my nipples, it's disgusting and makes me cringe inside, even now when I'm thinking about it. And it's the gentle touching and gentle licking that disgusts me the most. I also used to endure this horrible procedure but now I tell them I don't like it and I prefer my breasts being squeezed hard than any, and I mean any activity that involves touching my nipples. They often think that when your nipples get hard it means that you get excited and wet and ready for sex, but it's totally untrue.
