Perform a blowjob in a gallery space, a museum space is even better.
Instructions: You are among a crowd (friends). Get slightly drunk. Offer a man to get down on him right now in front of all these people you do not know. Fall on your knees and lick his crotch. Open his belt and caress his thighs. Be graphic. Pull his shirt. If he refuses follow him on your knees. Tell you are very good at it. Ask in front of everybody, if it is ok to perform in front of everybody and perform anyway. Be loud, say please. Ask why he refuses. Don’t you like it? Don’t stop, follow him. Be persistent. Say it is good fun and that you are cheap. If he is not willing ask why. I am not cheap enough, you ask. Say you are desperate. Say that you have heard you like it, I’m sure you’ll like it. Look at my mouth, say. Tell it is good fun and you have been dreaming about doing it exactly like this with someone like you. I like your smile. Don’t stop until you are removed and kicked out of the place for disturbance and continue to do it outside gallery space.
Another idea: Hire a male prostitute and go to a museum opening among people you do not know, maybe they are your colleagues. (friends and colleagues). When speeches are over and people are enjoying cocktails, themselves, choose a visible spot. Go on your knees and give the male prostitute a good old-fashioned blowjob. Don’t forget to swallow. Don’t stop sucking his penis even though you will be interrupted and told to get lost. Talk dirty, shout loudly and laugh, lick everything.
