Sex anyone?

Cassie
Our baby just turned 12 weeks Tuesday. We have had sex once, 2 1/2 weeks ago. We are both so tired becuase he is working days and I work evenings, plus I am in school for my masters degree. 
We are hoping to go get bed early tonight and enjoy our time together after she is asleep. It's weird to pencil in having sex. 
What are other people doing?
