werd, dude. weed makes my erections harder and I last longer.
One time I got a lil high before my gf came over and it was definetly good.
lol o-man you mad paranoid. aint no damn viagra pill laced in your weed nor is your dick gonna explode, LOL!!!
aint a black thing either, im white (talk like a new yorker hence my slangs) and my erections are just like you said when high.

weed can act as another kind of sex medicine different from viagra.
