one was my father and the only reason he told me was cos he going on TV abt it never actually discussed the details and practicalities wiv him , but i know he tried an injection 1st which gave him a permanent hard on for abt 4 hrs and he had to travel across london like that LMAO
the second was 'a friend' who had variable results wiv it
personally i think the best way is to take ya time caress , kiss and get aroused , take ya mind off it in other ways and it works naturally
