I do it once a year (gay pride)
I'm 42m, totally straight, married. However, my wife doesn't know that every year, for just one day, I head to the local Gay Pride festival and pick up guys for random quickies. I basically turn gay for a day. It's gotten more out of control as the years have passed--last year I took about a dozen meat pipes from behind in the bathroom of a local bar. I had more than a few milkshakes pumped down my throat too, if you know what I mean.
I don't even know why I do this. It's so degrading. I can't wait for the festival this year.
