I am a straight middle-aged man, but recently have been unable to stop thinking about what it would be like to be used by another man for sex.

A few minutes ago, I just placed an ad on a casual sex website offering myself to any man who would want to use me for unprotected anal sex.

I can hardly believe I actually did this.

And I can hardly believe that I know, deep down, that I will definitely go through with it if anyone responds.
