dear god what has cb come to... personaly i think if you need to drug your bf to get laid it will just be a whole lot easier for you to go and get it somewhere else. he obviously has issues as do you if your willing to go to this extent.
if you want to turn him into a rampant sex machine however hit him with MDA and a crushed viagra in a non alcoholic drink... he will either turn into a psycotic rapist or horny beast either way you will get laid... just depends how far you want to go.
