Expecting one or the other to be responsible for your performance is a bit sexist.
The point I'm trying to make is that your partner should not HAVE TO get himself or herself off, if you're there. If they want to, that's a different story. But they shouldn't have to feel it necessary in order to get off.
Of course the "different story" being, that if they feel the need to get themselves off vs letting you do it, I'm suspicious that it may very well be because you just don't have the right touch, and i would be suggesting parenthetically that it should be something you would want to work on.
I mean, isn't the point of being with a partner to pleasure each other? And isn't the point of pleasuring oneself because a partner is not around ? I mean, there's nothing wrong with partners playing with themselves as part of the session. But if it is necessary for them in order to get themselves off, then quite frankly, I have to say that I find that pretty pathetic.
And as far as your little "sexist" label, I was also thinking of men being with men. I for one don't like when I'm with a man and he starts stroking himself. I immediately take over, either with my own hand or with my mouth. In fact, a man I was with yesterday started stroking himself at one point. Which is what precipitated me creating this discussion thread. Because I take ownership over pleasuring my partner. I see that, and my mental reaction is "Hey, that's MY job". And the point of this thread was seeing if others can relate to that sentiment. Which obviously you don't, and that's okay.
