hole-some certainly, wholesome no !
This is a bacteriological minefield, but with an intimate regular partner of either sex, the flavour / aroma can be a real turn-on.
I have only been licked-out a couple of times as I recall, but neither experience was memorable. I have certainly enjoyed occasionally tickle-tasting my partner's arse hole, but with me even that is a matter of my mood.
