I'm 19 too and have the same pressure, i've been looking on the internet to see what it could be, maybe pelvis floor syndrome....check it out.
Ladies im so so so so so glad that im not alone! been to the docs today and she has no idea what it is - the more i research the more i read the same as what im reading here! Its crazy that no one knows what this is! Surely we are not the only women with this prb but like ive read everywhere, it seems to be put down to hormones everytime! But that doesnt make it stop!
I have a similar problem and can't figure out what the heck it is. It started shortly after I had a miscarriage about six weeks ago. It feels like a painful yet dull ache and it's not a localized pain... I can press, poke, and prod anywhere and there's no actual pain... just an overall ache/pressure feeling in my labia/vagina. I've had a physical exam and ultrasound and I do have a fybroid but somehow I don't think that's what it is... unless it is pushing on a nerve or something. The only thing that helps the pain is vicodin and I certainly don't want to be relying on that, especially since I'll be TTC again soon. This is driving me crazy!! I do have days where it doesn't bother me but most of the time I am constantly worrying about what it is.
Pelvic Congestion Syndrome
It's like varicous veins in the pelvic area and vulva and such. I had it a little with 1st preggy. More with the 2nd now just at the end of my period. The hormones cause the blood to pool there more so your more aware of it. It's like a heavy-ness, dull ache.
If you get what I do then it's just engorgment of all the veines down there. That's why sitting down helps :)
Oh, my goodness.... I am not going crazy afteral ! So sorry to hear you ladies get the same dull, heavy, dragging, achey feeling as me, but so relieved to know I am not alone. Sometimes it is so bad a have to sit down and lying down helps too. It is particularly bad after sex, so much so that I have to lay down for at least an hour before I can stand up comfortably. This all started during and after the pregnancy with my first baby. So, it´s been YEARS now and my doctor ( male), just tells me to keep up the pelvic floor excersizes etc. , that it will pass !
My husband and my doctor seem to tire of hearing about it, but I am in real pain even if it is not medically recognised.
Thank you for posting your comment and getting the ball rolling. I can only say that paracetamol helps me a little. Sorry can´t be of more help.

U may have prolapsed uterus. My mother in law had this and the pains that you have discribed as well as feeling better when she sat or laid down. so she had to have a hysterectomy and the pressure/pain is gone.
