Go to a public restroom. Pee in a stall, with the door unlocked, and standing at least 4 feet away from the toilet.

Go to the nearest woods and take of your pants, then run around for at least ten minutes. (You can choose whether or not you where underwear)

strip, and then jerk off into your underwear. Now leave your gooey breifs to be found by someone

this can be done in the woods or where-ever

Cum in your face in a public toilet. Only clean it once you reach home.

I dare you to masturbate through your pants on the next form of public transportation you are one. It can be in a bathroom if there is one, but you cannot change clothes until you get home.

spend two hours masturbating in front of a window

Go on a mile jog with a sharpie up your ass

wear panty hose with flip flops (so people can see your feet) and panties pulled up above the waistband of your pants

Tie yourself naked to a tree in your backyard for one hour.

spend an hour outside edging, then you may cum

Masturbate in a public restroom.

When you use a urinal in a public bathroom, let your trousers fall down to your ankles. If you're alone or just really daring, make your underwear go down that far too.

when you're alone (but someone could walk in any moment) strip completely nude (not in a stall), put your underwear in the sink, and leave them there. Put all your other cloths on and leave.

Go to a sex shop with a carrot up your arse and buy some gay porn. If you're feeling daring tell at least one person working there that you have a carrot up your arse.

if you live in a house, put on the opposite sex underwear and stand in front of a window for 5 minutes, if you live in an apartment building put on the opposite sex underwear , if male put on a skirt and top and walk down the hallway outside your apartment, if female, wear a long t-shirt and walk down the hallway outside your apartment
