So, my girlfriend has always liked me being constantly horny, having a really high sex drive, and always being more than happy to cum for her. It makes her happy, and I like that my pleasure makes her happy too.

But I've slowly seemed to become more and more depressed. No clue why, and it sucks. I don't have any medications at the moment, no antidepressants. And yet, for whatever reason my normal extreme frequent horny has completely died. I don't enjoy it at all. I have trouble even trying to put myself in the mood, and I don't even want to cum. I think she's beautiful, I am very attracted to her. But she used to make me horny by laying a certain way, and now full-on boobs don't do anything?

So can depression fully kill my sex drive without even taking drugs? And if so, how do I deal with that? I want my sex drive back. I can tell she's frustrated with it, and I want to want it again.
