why everyone want to buy viagra?
normally viagra is a drug for people who are >50yo and have erection problem.
it's not really useful for young people.
btw did you guys check in a sexshop, most of sex shops in europe sell viagra and other poppers, maybe it's the same in hk
viagra is useless if you drink too much alcohol, so don't use it if you are planning to use it with a ktv girl
and a little advice, do never eat viagra if you also use poppers
