Sanguinely.

You can't help but be a little impressed by how easily the servant rolls the ring into place, giving your balls a light fondle as she demurely buckles up your pants.

As you walk around, getting used to the odd sensation, you find yourself actually enjoying it. You're not aroused by it but you definitely think you have a better understanding of how orgasm denial should work and how sensitive areas feel when they are constricted.

However, this party has altogether too many exciting opportunities that require the full mobility of your junk so you spend a minute or two wiggling the thing off in an unattended corner. You pop the ring in your pocket. Might come in handy later, you never know.
