Everyone has their own special kind of kink, whether you want to admit it or not. I have done it with a very special lady and we both kind of got off on it. I have had a very special lady not want me to go down on her after we had been at it a while because she thought it was not appealing since she was so creamy on her own.
Personally, it is probably better than a "Golden Shower" or having a "Hot Lunch" served up. Neither are of an even remote interest to me! Being nonjudgemental though, if it turns your crank then go for it!
To each his own. Whatever your kink . . .
