Thanks for the support everyone.
Jelly-Bean: I am 27 years old. I am not on any anti-depressant meds at this time. I'd tried several brand when I was younger and in high school, but they never did any good for me so I stopped taking them about 10 years ago.
The_Skeezyks: I think you may be right about the "snowball effect." Sex tends to hurt, so then the next time I'm worrying about how it will hurt, which keeps me from relaxing and being able to enjoy myself, so then it ends up hurting even more, and so on. I've been working hard to use positive self talk and not get trapped in these self-fulfilling cycles, but progress is slow going.
I'd love to go see a specialist or an endocrinologist, but with no medical insurance, I really can't afford it. The one blood test (thyroid level check) that I had done was thru a free clinic. I'm not sure if they can refer me to a specialist or not...
As for stress reducing things, I have been actively trying over the last month to do better and be better to myself. My job - (which I love, and isn't really a stressor beyond getting frustrated at stupid people and their stupid first world "problems" that aren't really problems) offers free yoga twice a week. I try to go twice a week, but it's usually just once a week that I can make it. Recently I've also been indulging in bubble baths to relax. I have a glass tabletop that I put across the tub, then I can use the laptop to watch a movie while I soak in the tub. It's quite nice and very relaxing.
WantToGrow: I am indeed on birth control pills, have been since before I met hubby. I've had several different brands over the years, and the new supply I just got is a new generic brand, so it'll be interesting to see if that affects my libido at all.
I used to like porn, and erotic literature is a favorite of mine. But lately even those things don't stimulate me. (Also, most of the "erotic literature" I find online tends to suck now-a-days. Crappy writing, no character development, piss poor stories, etc.)
This whole "gluten free" craze amuses me. Only those with celiac disease can't digest the wheat proteins. They are the only ones who should be "gluten free". The rest of us could probably do good for ourselves by cutting back on the amount of wheat we eat (evolutionally speaking we don't need as much wheat as we tend to intake in these modern times) - but going off gluten entirely doesn't make sense unless you truly have Celiac disease. I think South Park got it right, but that's just my opinion. I hope we're both able to find things to help us with rebuilding our desire and libidos.
