I wouldn't bring it up tonight, and I would probably discuss it with your IC or a DB coach first. As an LBS, as you know, you *do* have to put in a lot of one-sided effort for a long time. The important thing is to make sure that "long time" is not forever.
The challenge with bringing it up is that if she is physical with you only out of a sense of obligation, you'll know that and it won't be enough. You'll want her to *want* to be with you, and that's not something she can control.
Reinvigorating your sex life is something she needs to decide she wants to do, and getting there requires starting slowly with some building up to it. It's all about her mindset however. If she's not committed to it thinking that it's the best thing for both of you, you'll know and you won't be satisfied.
I would discuss with the IC first.
