Hyposexual activity - voluntary or non?

I always hesitate to write about my sex life in here for two reasons. First, there are people who read this that I don't want reading about it (ie, little brothers and ex-boyfriends). Second, there are people who read this that know me and my boyfriend very well and they probably don't want to hear about it. But hell, I've met the Lad and Tara's escapades have never bothered me. So here goes.

People always say that when you take Abnormal Psychology that you will diagnose yourself with half the psychological problems that you learn about. Very few people are actually like my professor, who is indeed OCD, anal, and slightly homocidal. I've actually come up with two personal diagnoses:

First (and this is really hard to finally say outloud - I've only mentioned it to two people in my entire life), I am chronically depressed. Basically that means that I don't have major depressive episodes, but more of a low-level consistant dysthymia. My life gets in a cyclic pattern where I am okay for a few weeks (even exceedingly bouncy) and then there are some really low weeks. I cry a lot (sometimes for no reason at all) and am not motivated to do much of anything. My closest friends have seen these patterns, but who knows what anyone really thinks about them.

Secondly, onto the sexy part lol. My sex drive is just kaput. I've been with my boyfriend for almost eight months now, and for the last month or so, I haven't been giving it up. For some reason, I've lost that drive recently. I started writing this, thinking it was my own fault - that I've messed with my own head in a way to get me disinterested in sleeping with my boyfriend. But, actually, by writing out what my first problem is, it could be the reason for my second. When my emotions get in a slump, my body does too. I mean, I guess that makes some sense. In my silly head it does.
