lol... "get my dick out & masturbating to porn." Sound like something you'd do on adderall & not weed. But to each his own I guess.
ALWAYS, I will listen to music while in the process of getting stoned. I smoke everyday, I have been for the past 5 or 6 years & listening to music while toking up has never gotten old. I think you really have to enjoy music in general though to not get tired of doing that every time. There is just something about music & smoking that is wonderful... It is like a ritual for me. AFTERWARDS, while I am stoned, I'll usually play video games, browse the web/youtube, eat food, or just do my normal everyday activities.
I really miss the days though when weed was so new to me. It was really mysterious. A friend & I would actually plan out where we were going to smoke (mostly outdoors.), when we were going to smoke, what we were going to do after we smoked. Which would usually consist of walking around town & just feeling like a young kid excited to be doing absolutely nothing but walking around & looking at stuff. I'm not sure if these are the correct words but it felt so innocent & so playful.
Some things you could do instead of beating your meat: 8)
-go to a favorite restaraunt of yours, try walking there if it is closeby, (driving while high is NEVER a good idea, IDC how good of a "stoned driver" people claim to be.)
-go to the park
-go on a walk around your neighborhood (or if you have an "in town" area where you live go there with a few bucks in your pocket incase you get hungry or thirst.)
-go fishing
-have a barbecue (by yourself or with friends & family.)
-go skateboarding
-paint or draw some pictures if you're into artsy type stuff
-go to the beach
-watch your favorite movie
-go see a local band
Hope you find other things to do instead of choking the chicken everytime you get stoned.

Take care!
