Perhaps I should let Lady Amanda respond to this -- I can only assume her reasoning on this issue -- but I'm awake and she's not, so I'll take a crack at it.

You're right, it would be additionally humiliating, especially if his erection was on display. The problem that the good Lady saw was that without some means of preventing him, the young man would soon have an orgasm...and no erection!

I think the general consensus of the posters on this thread is that the poor fellow isn't to be allowed to enjoy himself. Erika thinks she can prevent this through the force of her will (which I would never presume to dispute!), while Lady Amanda and I would prefer to rely upon a lock and key.

After reading through the thread three times, I noticed that denisjames specified that the fellow shouldn't WILLINGLY enjoy his servitude, which is rather different from what I had assumed (that he not enjoy it at all). Now you've got me curious, denis -- is he to be allowed to orgasm? Maybe if the circumstances can be arranged to be particularly embarrassing (ie. your photographic evidence)? What's your take on this?

(For that matter, if I've improperly spoken for either Erika or Lady Amanda, I expect to receive a sharp reprimand!)
