No sex drive... None!

I'm 33, we are TTC, but I don't have a sex drive at all. A systems down, not even a thought of sex. When we do the dirty, I don't even get into it. It's been about a year like this. I'm very much attracted to my boyfriend/fiancé, and we've talked about it, he doesn't really have much of the sex drive either! We used to have sex all the time before I bought my first home. Stress isn't as bad as it used to be, I want to get aroused but my body won't let me. I thought maybe some testerone might help, I don't know. Any suggestions? Even for play doesn't help. Please help a sexless woman out!
