I am not OP but I am very familiar with EDS and many related disorders.

Growth hormones would not be of help. More cells =/= stronger skin unfortunately. EDS is suspected to be collagen synthesis disorder and if so, therapies that upregulate collagen sythesis (ie gene therapy) could potentially help.

Medical Lab Tech's are in high demand right now in the US and will continue to be for the foreseeable future. There are community college programs that offer a 2-3 year degree program for cheap but they sometimes have long waitlists. If you don't go private, I'd recommend adding yourself to a waitlist just in case.

I've also had it and used liv2. It's good but I highly recommend looking at glass toys as well. There's a lot of thin ones out there if you look around and being near frictioness when used with lube, your muscles seize less with penetration. If you're not at a point that penetration is on the table yet that's fine too but clit vibrators (if you don't have vulvodynia) and wands are good too. My physiotherapist recommends using vibration in combination with penetration/dialation work as it's easier for some people.

Even if you choose to wait until marriage, she needs to start working on & figuring it out now. The anxiety & avoidance just becomes stronger when you put penetrative sex as an expectation for your wedding night. A lot of couples talk about this and address this in /r/vaginismus.

Check out /r/vaginismus (support community for a variety of female pelvic pain and vulvar issues). Read when "When sex hurts" & 'ending female pain'. They're cheap and worth reading. Rule out STDs, basic infections, or anatomical abnormalities. If you're in the clear for that and you can, get into physical therapy.

PS Data shows that a lot of women with vaginismus (not vulvodynia which OP has) disproportionately come from conservative religious backgrounds. Sometimes these backgrounds result with someone growing up with a 'premarital sex is shameful' attitude and don't know how to 'turn it off' once they get married. I'm not saying that is at all what is happening, I'm just saying its something that does happen and its unfortunate.

What do you think is one of the most important things the average person can do to preserve or improve their spinal health?
