I understand what the OP is saying but don’t agree with the motivation.
Because I don’t know my swing partner as well as N, I find that I have to be on my A game more to make sure she is totally satisfied.
With N, it comes easier since we know each other so well, but I definitely want to make sure she is as satisfied as anyone else that I spend time with. Not only that, I have yet to find someone that kisses as good as she does (again, maybe we are so used to each others style), and I LOVE to kiss.
Mr. (can't wait 'till the N get's home so I can lay some lovin' on her)
