Motives:
Well... Tease a guy might be just as good a reason to be in the game, as getting a number - we all have our motives...
and because bombshell is a girl, I think it is easier for the 'poor, confused guy(who were probably thinking: "Score, I did it...")'... but what would girls think about me, if I was in the game, just to work them up, to the point, where they thought: "this guy is so sweet... he seems interested in me... he might be BF materiel"... but when im done undressing her... having kissed her a little... I look at her and say... "it's not going to happen..." - she would be confused and feel sad... "what did I do wrong... we had it... why did he refuse me... is something wrong with me"
But motives put aside - what happened:
I think neither of you won! - and it wasn't a draw either... I think both of you lost... and maybe you lost the most...
like Jaybot pointed out, your sex (good as it might be), isn't that interesting for a guy of quality, he IS able to find someone else, who will offer him whatever he needs (not saying you should have had sex with him)
I think you SHOULD tease him... but not by 'lying'... I believe, that you with all of your bodylanguage and actions said: "it's now cowboy... let's get undressed"... and when he showed you his affection (:D) you pushed him away.
I think, that the push-pull effect was to powerful... and due to the 'quality-guys-get-what-they-want-theory' I think you might have lost him... unless he's not... but YOU wouldn't waste time on a guy, who's whimpy and easy to control... (or??)
Hypothetic situation:
well... you did accept the invitation... and it's not, that you didn't know his intentions... but...
you are in the room(his mother's???) with the guy... he starts to come onto you... he begins massaging your neck... you allow this.. and enjoy it... PULL
he tries to escalate... tries to kiss you... you put a finger on his lips and say something like: "these lips aren't for any guy, you know" or "you have to try harder, if you wanna go there" - both in a flirty way... PUSH
continue this... for as long as you like... and allow him to escalate, when you think it's okay... but...
Don't give him permission to something... and then take away that permission... it creates confusion and destroys attraction by replacing it with frustration...
the mysterious girl is attractive
the confused girl is not
you should have push-pulled him until you thought it was enough for that day... put you telephone in his hand and said: "type in your number, so I can call you some day"... or if you are the kind of girl, that like the boy to take the initiative... given your number to him...
Then you would have WON!!
