(NSFW) A question for the fellows and "afternoon delight"?

Curious, for some women (maybe, most?), right after an orgasm (say, 10 seconds) the clit is very sensitive. So sensitive that it feels good, yet is slightly uncomfortable (too much), if someone continues on with oral.

Is it the same for guys? Right after they’ve cum, if a woman (or man) takes them in their mouth, is it also quite sensitive (too much)?

I have watch a bit of porn in my day, and I’ve noticed that after a guy has cum and a woman continues on with oral, there is quite a reaction out of the guy. Almost as if it is too much?
