I received a massage where the provider manually stimulated me as well as kissed, sucked, and licked my nipples for a few minutes and then when she was done, gave me a peck on the lips. My lips at the time were severely chapped. What is my likelihood for contracting HSV or anything else? 

I should also mention that I have previously tested negative for HSV1 and HSV2. If the provider did have herpes, what is my likelihood? 

I think the likelihood of your contracting HSV 2 is zero and the risk of acquiring HSV 1 is just about the same.  A peck on the lips is simply not enough contact for the virus to be passed to you, especially if she didn't have a cold sore.  In terms of the nipples, I would recommend that you simply observe them for a week or so and if something abnormal shows up there, have it swab tested.  Again, herpes of the nipple is possible, but quite uncommon, for sure.---

Just to clarify, even if the masseuse had a cold sore, because of the type of exposure (peck); the risk would still be close to zero or minimal? If so, could you delve a little deeper into why that is? 

the risk is still close to zero because a peck dos not go beyond the thicker skin of the lip, right?---

Yes I suppose. For my understanding, when children are exposed to HSV from a relative, how are they getting it? I would guess that a relative isn’t doing anything more than a peck. 

I think that depends on the nature of the kiss and the age of the child - small children have less keratinized lip skin that is more vulnerable AND their immune system may not yet be as good to defend themselves against HSV---
