sounds to me like you are just rebounding and still resentful for not getting the first guy... nothing to do with scorpio.
if your heart and/or attention is somewhere else, after the treetrunk or date you still going to want what you feel you are missing.
I don't get the feelings so fast?
unless he treetrunked you like I treetrunk mine... I do it for a control thing though. Sags are pleasers....but I have a scorpio rising (ascent)
Truth of the matter is, if I jump in bed with someone too soon, I'm not interested afterwards (definitely after 2nd go round)... All my relationships longer than a month were with girls I actually talked to for a month or two before the big dance.
