Burning bits! Eek!

Hey all, it’s me on the moan again lol.
Just after some advice.
Hands up if you ended up with burny bits.
My foof feels a little sore, but when i pee it is very sore. Its almost like cystitis but not if that makes sense. Its more spread out. Boy this is a pleasant post. Sorry haha.
Has anyone else had this? What did u do?
Im worrying as its only wk 2 of the radiotherapy so im hoping my foof doesnt burst into flames by wk 5 lol :-o
Big love xxx
