I'd absolutely have sex when I'm high but I don't like to be high around my girlfriend. I have only by accident (she had plans, I smoked, her plans fell through, she came by, sexy time) and of course it's awesome.
I've also noticed I never want to eat if I smoke with other people, the hunger seems to never hit, but when I'm alone it does, I guess it's lack of stimulus that makes one wonder. People in general eat more when they're bored.
I'm kinda pumped for the next 20 days, I hope you guys are too. I guess I might as well start sprinting again too.
