A person's once in a life time is just that until an even better once in a life time shows up. Perhaps the a more accurate option would be to have the ability to go back, and change the first once in a life time to a 9. The way things are set up, that's quite difficult to do.

Well, yeah, if taken quite literally, once in a lifetime only does allow for once.  But the rating system here is probably more flexible and forgiving than that.  I know that on more than one occasion I've enjoyed 'once in a lifetime' experiences, and I'm hoping for more of them.  If it were outside of the opportunities afforded by this pastime, for me, they would probably be 'never in a lifetime' experiences, or at least 'not bloody likely in a lifetime' experiences.  I think its fair enough to categorize the really over-the-top spectacular experiences as 10s, simply because in real life, you may very well would never have had even one of these opportunities more than once, this not being real life and all that...

So, I'm looking to experience as many 'once in a lifetime experiences' as I possibly can!

Lets say five years ago I saw a gal who I gave a ten. Up to that point she was a "once in a lifetime experience.  If she retires from providing are you trying to tell me that there is no chance I will ever meet a provider who does a better job of rocking my world?  That just doesn't make sense in any way.  Life and hobbying are fluid endeavors. You can't take the numbering system that literally.

Re: Review Self-moderation

that would be a one in a lifetime up to that lady what comes next can be as good or better...I believe 10 should be given sparingly ...some reviewers give 10 one after the other and that does not really make sense

What idiot would go back for seconds?

I gave a duo visit a 10 (once in a life time) because it was most likely a once in a lifetime event, I am sad to admit that I am not man enough to do that again.
