I have always been aware, focused and concerned with my partners pleasure & climax. Her orgasms only increase my pleasure and can at times help intensify my climax.
My ex couldn't reach the peak without a lot of attention and that normally meant using hand held aides. I was never against the time and effort to bring her over the top, but she would become concerned i would resent having to spend the extra time helping her achieve the "O". I never did, to me it wasn't an issue.
My current lady has no problem reaching the peak & usually is there before i get there.
She is multi-orgasmic but i still stay aware of her pleasure needs.
I agree that reaching orgasm isn't the one most important detail in sex, but if and when it happens, it does make everything better for both.
Talk to your partner, listen well to what she says, discuss it at every opportunity but don't make it the end all conversation. Mention it casually during foreplay, pay attention during intimacy and don't forget the all important afterplay! Your partner is the only one who knows how important it is to her and the best way to help her achieve it.
