Yes Or No
To me most taste pretty disgusting to be honest with you. I would rather taste a ( clean ) person.
Sugar is also bad for the PH balance of the Pussy. assuming you are going to move on.
But it does mean you can move on smoothly from foreplay. so yes,maybe they can have their place.
As far as licking of Vagina. I can say it becomes more tasty when doing it with some lubricants.
I thought it may be the case with flavored condoms.
