She wants out of a session as quickly as she gets into one or as in she gets bored quickly?

We switch, but I tend to be the dominant normally, so it's hard for me to play sub. DH has to spend a lot of time talking me into the bonds, then the hood, then the gag, etc. I always fight it initially and resent being caught until I get distracted by the pleasure. If he doesn't get me flying quickly, it doesn't end well. It has gotten easier lately probably through his patience and the fact that it does feel good.

If it's more boredom, then you'll have to keep things interesting for her.

If in general you're trying to make her more patient, the games may help if she's properly rewarded at the end. Good things come to those who wait, right?
