May is masturbation month. Would anyone be keen on a masturbatathon?
The idea is a group of people get together for solo masturbation only to collect money for charity (something vaguely relevant - not a children's charity or the SPCA). Could work by sponsorhip and/or an entrance fee. To try and encourage women to participate and reduce the chance of turning the event into a sausage fest women could enter the event free of charge and men have to pay say R100 or R200.
Raincoats, umbrellas and gumboots would be optional.
