Is it normal i refuse to orgasm before the woman during sex?

As a man I refuse to orgasm before a woman does when we're having sex. I believe that is my responsibility as a man to make sure that the women receives maximum satisfaction and pleasure in bed, therefore I prolong my own orgasm for as long as physically possible. Even though I am well aware that women can experience multiple orgasms, I still consider it dishonorable to orgasm before she does.
