Yep that's the stuff you need.
Well I went to the doctors and they think it could be thrush and recommended I pick up some Canesten so I'll see how that goes over the next couple of weeks.
I'd see a doctor first they'll be able to recommend a course of treatment.
Thanks! Any idea what I could do myself to treat it if it is a fungal infection? Anything that could be bought in the shop?
Sounds to me like a fungal infection which isn't an STD. Definitely recommend getting seen by a doctor to make sure though. Use protection next time my friend.
