When your partner respects you, he cares about your pleasure.
When did this selfish behavior start?
Was he doing what you needed to get to your orgasm, and giving you enough time before?
Did things change after the wedding? (In other words does he think he doesn't have to try now that he has you in a situation where it would be difficult for you to get it from someone who DOES care?)
Did he stop giving you what you needed recently?
Was he always a selfish lover? If so, did you think things would magically change?
WHERE and WHEN did he get so selfish? Or was he always this way? IF he was always this way, you have a LOT of thinking to do.....
