Do you think it's OK (or too weird) for a man to want to spank the bottom of his female partner and then kiss, lick, bite, and suck her punished skin?
Weirdness, like beauty, lies in the eye of the beholder. The answer to this question depends upon the couple and their preferences.
Randy sometimes kisses my bottom after he has spanked me. I believe he intends this gesture as a loving tribute or simply an acknowledgement that he likes my shape, hue, and texture. Immediately following a spanking, I have no objection to a kiss at either end (or any number of other activities involving physical skin-to-skin contact).
But I speak only for myself. This is a situation where talking through your desires is essential. For example, if biting is a hard limit for her, you will want to respect it. On the other hand, maybe she'll say she loves it.
In summary, as long as you both enjoy it and no one gets injured, what anyone else thinks is irrelevant.
