I`m at that age where I need a bit of help, plus i don`t wan`t to waste money on paying for a punt and not being able to stand to attention.
I take it about 40 before the action starts and has kept me going for well over an hour in FFM thresomes no problem.
When i`ve been single ladies half my age some have commented about my ability to keep going for so long,,,,, never told them about the chemical assistance though.
