OMG, Kim! The cramps are "proof" that I could do without! But I do understand why you'd say that!

So...let me know if I'm asking too many questions...you're intersexed, is that the correct word? But you're going through puberty now? You mentioned that you were on HRT for awhile, do you suppose it could've "reminded" your body of the hormones it's supposed to be making, or is that too sci-fi? I hope I'm not being too nosey, it's just that I'm fascinated with bio-chem and microbiology as it affects the human body. That's why I'm in the Med Lab Tech program at my college.
Your wife sounds like an outstanding person. I'm very happy for you both! I can only imagine the shock all this must have been for you both, especially for you. You seem to be a lot happier now than in your first post, though! Are you relieved?
By the way, back to that cramp thing...I know that you're not actually bleeding, but it might be possible that you have uterine lining growing on internal organs as it normally would in a monthly cycle. It sheds roughly once a month when certain hormone levels dip and others increase. One of these is prostaglandin and it causes cramping. However, in endometriosis, cramping is much more severe because the lining is growing on and shedding from inappropriate places. This isn't a dangerous condition and many (although it can only be firmly diagnosed by exploratory surgery) have this or are suspected of having it ...but it could explain your sever cyclic cramping.
Some big-sisterly advice (I know, I know, I would be a little sister to you, but technicalities!): Try soaking in a bath with Epsom salts, cut down your salt and caffeine intake, increase your water intake, try a hot-water bottle on wherever you feel the cramps, and if you must, pop an advil (I save it for last because I dislike taking medications unneccessarily, that's my own bias!)
At least you should get more sympathy out of your wife than what some of us ladies get! For example, I only got the look of fear from the guys I've dated. It was kind of a deer-in-headlights look and then they would flee and I wouldn't see them for the rest of the week. But Josi, she's sweet. She would feed me ice cream in bed for the entire week if I even hinted that it would make me feel better. Hopefully, this will work for you. Okay, I've rambled too long. Later!
