hmmmm...i really don\'t think it does, i wank off all the time when i am stoned and i stay high for hours. actually, it seems that weed makes it so that i can get going after i finish in a shorter amount of time. but i don\'t think sex/masturbation would kill your high.
its weird as fuck everytime i get off my high goes away and i have a little body high.its fucking gay cause i love porn when im stoned lmao!!can someone research this im kinda lazy at the moment lol
