I usually buy my Indian made V in pharmacies in SE Asia and bring a supply of boxes home in my suitcase. I've never had any problems with customs!
I don't use it all the time as I ,, get a much stronger and sustained erection when I do use it.
My supplies are running low and I'm not planning a trip for awhile so I might try some of the websites McLuvin suggested.
one more thing, I know a young lady who takes a V sometimes. She swears that it makes her clitoris feel bigger and more sensitive and gives her a more intensive organism. Have any other ladies tried V and has it worked for them?
