This is very strange and embarrassing. Despite all of our combined health problems, OH and I actually managed to have intercourse last weekend, with the help of YES oil-based lubricant.
Anyway, all was fine until Wednesday afternoon when I started to get very itchy down below and OH informed me that he was the same

The only thing we can think could have caused this is the YES, which very stupidly on my part (no doubt as it is used so rarely) was about 8 months out of code and originally opened probably a couple of years ago

Everything points to thrush, but this is not something either of us have ever been bothered with and so I am thinking that it must be through using the old lubricant.
Could it have caused an allergic reaction do you think?
Am putting on Canestan cream that I had in the drawer (also out of date) to try and calm things down.
Was even considering ordering us both a Fluconazole tablet, but not sure if this is a good idea. Has anyone tried these?
