well right about this moment this is how I see it.
Non commited sex is nothing more and nothing less than two people using each other for their own selfish reasons. Not a bad thing just thats the mechanics of it right.
Man and woman likey the orgasm. So as long as that part is understood between both what is the difference when you incorporate weed into the picture?
The orgasm isnt the only gain in any event,the list is neverending why people use each other for sex. So whats the harm in him gaining weed? No different than her gaining whatever she may gain.
If nobody is being taken advantage of no harm done.
Its a give and take.
enjoy your weed.... oh yeah right sorry i forgot it was your 'friend' who wanted to know...hehe
