My partner has a lower sex drive than I do. Even if we have sex, I end up masturbating at least three times later in the day-- which is honestly not as satisfying.

We've talked about the difference in the levels of drive and he seems believe that I should lower my sexual appetities to his level.
He said he would try to have sex with me whenever he is turned on, but it still seems like I'm the only one initiating it.

Are there any other ways to help him increase his sex drive or diminish mine? Or to encourage him to have sex with me more often without overexhausting him too much?

We've talked about our sex before-- we both enjoy it. I've asked questions on my performance and if he wants me to do more or less but he says everything is fine.

Cheating isn't an option.

Help?
