If you're going to masturbate, don't be selfish. Do it for a cause.

Yes, according to a Reuter's story, hundreds are expected to attend a masturbate-a-thon in London today. Sponsored attendees will be jackin' or jillin' off to support HIV/AIDS awareness and prevention. The amount of money raised will be determined by how many minutes you masturbate and/or how many orgasms you achieve.

According to the story, "Participants, who have to be over 18, can bring any aids they need and can take part in four different rooms -- a comfort area, a mixed area, along with men and women only areas... However, the rules on the event's Web site states there can be no touching of other participants nor are people allowed to fake orgasms."
