I was going to namechange but this one is relatively new anyway so meh.
I'm going to try and explain as best I can
. About two weeks ago I woke up with what I can only describe as a really full pelvis
it felt like when your in labour and the babies head is just about to crown (but not painful). Felt very full in my bum and vagina felt engorged. Clitoris was pulsating and really really sensative. It all kind of felt like I'd spent all night having sex (was in bed at 9 and hadn't!).
It got progressively worse all day until I decided to have some me time (thinking maybe I was just horny). That sorted it for a few hrs and then it gradually came back. But with occasional bolts of what I can only describe as about to orgasm through my pelvis/clit/bum 
This has been going on for TWO weeks. Some days worse than others, but pretty constant. TMI coming up but I can squeeze my legs together and make myself orgasm without touching myself.
I promise I'm not a troll (cods gavel)!
The only other symptoms are it's a bit stingy when I go for a wee, poss UTI?
I had thrush about 3/4 days before this started
And I have a weird pain in my knee and that heavy cramps feeling you get in your thigh when you are having a contraction.
Any ideas?
