So i'm in need of some help!

So my daughter was born 2 years ago and ever since my sex drive has been completely out of whack. Would go periods of time without having sex and its putting a strain on the relationship. Trying to figure out anything I can do to boost it up.

I want to just as much as him, but if I'm not fully into it, I don't want to do anything just because I know he will know if I am or not and it'll turn him off.

Any tips on boosting my sex drive?
