Fucking cystitis again

Well, whaddya know, I've got cystitis again. Had two lots of sex last weekend, and the second lot was a bit rough, and he hadn't showered beforehand. Developed cystitis on Saturday night. Took herbs, salty water and paracetamol. It cleared quite a bit on Sunday. Monday no cystitis and had acupuncture for the hives. Tuesday, cystitis stinging and rode bike to work. Tuesday night really sore. Took herbs and salty water. Felt better yesterday, although could still feel it. Then today, felt loads better. So had a cup of coffee like a twat this afternoon, and think it's that that has caused it to flare up right now. Mental note: he needs to wash his cock before sex.
