yes i have experienced the same effect on codiene which now is my only real opiate taken in very high doses and i get shrivel dick from it also but i think its because while on it at high doses the last thing i think of is sex plus im on alot of benzos which seem to do the same.
It takes my libido away hence the shrink dink but if i dont do anything for a day which on occation a do go without anything cept my clonazepams im back to normal.
But even on opiates or benzos when hard its the same as always.big and fat lol lmao.sorry girls dont wanna scare ya......lmao
