We just can't seem to have simultaneous orgasm and I'm getting fed up. Are we normal?

Only one third of couples have ever had their orgasms at the same time.  It’s lovely when it happens, but don’t make it a goal in itself.  Sex experts agree that we all enjoy our orgasms more if we have them separately, but why?  Because then you can enjoy the other person’s pleasure when he reaches cloud nine, whereas if you come at the same time, you will both be alone in your little worlds without sharing.
