OMG I'm laughing because I just read a blog post about this...
You are going to think I'm either crazy or lying but I swear I'm neither.
You should buy plain (not vanilla, PLAIN) yogurt and of course you can eat it but you can also just PUT IT ON YOUR NETHER REGION. I even read that some women put them in those ice trays that freeze cubes into long tube shapes, the ones for putting ice in water bottles, but they put the yogurt in the ice trays and then the frozen yogurt, when it gets inserted into the nether region (sorry, VAGINA) it is a huge relief to the burning sensation.
I know you will think I'm a nut job so here's the link to the blog post I read! (Be sure to read the comments too.)
