You don't have to let her hanging, you can please after she pleases you...
For instance if I climax before my partner, it brings her to a higher level of arousal and she tends to come easily after that.

There is an entire movement with pulications on "ladies first." Being a woman, I think it is great. The premise is that the woman's orgasm is more complicated and iffy than the man's. Plus, the endorphins get to man and he ends up drowsy and disinterested after his orgasm.

Those are the essentials of the argument and in my cohabitations with men, we usually did me (her) first. Excep, of course, those times when I was really "doing it for him" and had no intention or desire for an orgasm. In those cases, I simply took charge and he had no question what was going on - just enjoy.

The only wrench is, if she has a difficult time coming, just come first yourself. Then either (a) she won't expect reciprocation if it's a 'quickie', or (b) you can take the time to recuperate while you're getting her off, so you can do round 2 immediately afterward

"Ladies first" works well especially for those who are not multi-orgasmic but there are times when, as Brandye has said, women have a different agenda.
Being a gentleman is more about making sure she is happy, comfortable, and satisfied than anything else whether you come first or last.

I agree.
I hate to be left hanging.
If my husband isn't too tired we might have a second round even where he rests while I shower and he will go down on me. Otherwise he holds on. Poor dude - I can take ages to get there. But we enjoy the playing and that is most important to me. Sometimes I can O twice.

I always try to bring my wife to orgasm first, firstly because I feel it's nicer for her because I can only go once - and secondly because I have self confidence issues and it takes the pressure off worrying about "performing" (not that I always worry) because of that I love to use my fingers and various other parts on her to build her to a frenzy.
