I like Unaluna's perspective about "I survived, now procreate!" I also second the idea about getting a sheet or something to hang at the doorway, if you don't already.

Have you increased, decreased, or changed medication recently? That might have something to do with it if you have.

It also could be your age. Your cycle. Really, who knows? Does anything here resonate with you?

I miss having a higher sex drive. I used to masturbate everyday. Now that I'm on lexapro I'd say its gone down to about two times a week. I understand how frustrating it would be though to not have privacy like...a door, and living with parents, when it comes to that kind of thing.
