The problem within your relationship might not have been a problem for everyone. Unfortunately, given your makeup, it was for you. You lacked heat together.
Lusty, sensual being that you are, you've felt the zing of a hot physical connection before, and this wasn't it. When you kissed you didn't feel butterflies, in fact, you had to work to feel anything at all. Worse, your lover tended to be somewhat cold, withholding the easy affection and cuddles that might have made up for a lack of ardor elsewhere. The answer lay, surprisingly, in your past. Why were you so intent on showing your love physically? What did it mean to you to have a lover who yearns for an erotic connection with you? What insecurities of yours were tweaked by a lover who could resist your wiles -- and just who in your past did this attraction/repulsion, push/pull scenario remind you of? If you had decided this relationship was otherwise worth it, and were able to rid yourself of your emotional baggage (as well as your knee-jerk desire to wrap your lover around your little finger), this relationship could have been blessed with lasting stability. The power was within you.
