Does Viagra sorta numb the penis when being used delaying ejac? This is what I heard somewhere. My girl HATES condoms and so we have yet to use one, and it is hard for me to hold for long. I can go for a bit, but Im done, when she is just getting into it like 5-10 minutes. Never had chance to practice holding back, but I knew all the tips they just didnt come to mind
