I am wondering what the point would be with - or without - the saran wrap.
I will take a wild guess and say, to give pleasure to the woman, like a CBJ
or BBBJ gives good feelings to a man.
But for others maybe it is something else they are looking for when they
give daty to a woman, like some form of compensation, or the sensation
they got when they were a kid eating a slurpee, i don't know.
If the latter, why not try pina colada flavored lube on the saran wrap.
As far as the sensation for the woman with saran wrap vs no wrap, i have
a strong opinion that it would feel about the same, just as a balls massage
does with or without medical gloves.
