You'll never guess

If someone is suitable for the orgy, I send them a message with some details and request an email address if they are interested.

My best estimate is that 75% of guys respond with an email address and so get onto the long list.

Once i send the invite, the response rate to that is about 50%. I mark profiles who have not responded to the initial message or the invite with an unhappy face, so that I can keep track if someone asks again. (There are currently 427 profiles marked like this!).

I don't mind people not responding. I have to say no to alot of profiles, so I'm happy when I get a no from someone else. I prefer enthusiastic attendance to forced participation!

I've given up trying to predict who will respond to the message or invite and who will not. A profile of an exceptionally handsome guy will say yes and a profile which I was unsure about will say no.
Guys who have messaged me before the invites are sent, saying how excited they are about coming, will not respond and guys who are a bit muted in their communications will respond.

However, looking back at some of the profiles which have not responded, I am sometimes surprised - firstly, that I said yes in the first place and secondly that they didn't jump at the chance!
