I don't ever get aroused thinking about my exes, but I think about them from time to time when a memory is triggered. Sexually, I'm basically lucky, because Becks is more fun in bed than my exes had been. She's a real screamer and easy to please.
But the most important part is, I feel warm and fuzzy inside when I please her, in a way I didn't feel like with other girls. Pleasing her means something to me, something other than just thinking how great I am in bed. Before it was about conquest and feeding my ego. Now it is about love and wanting to make her happy.
