i'd try to figure out what to say to her, then change my mind, then change my mind again, then start thinking of something else, and eventually she'd just say "hey, you haven't spoken in 20 minutes!" and then the moment would be over. shit, i'm 27 and i still don't really know how to pick up women.
you just go up to her, tell her you like her and pull down your pants What's the worst that could happen? She says no?
Next time you're smoking weed with her, say something like, 'Hey, I understand sex is awesome when you're high, let's try it ok?'
Aw man! You ain't got your bidness straight yet??? Seems like being high together would be relaxing enough to say it. Meh.......
yes and no. it probably won't lead to immediate boning, but it will remind her that you're a male with sexual urges. it's important to keep that thought in girls' heads, or else they'll start to see you as a girlfriend.
