Since a week ago or so, I've felt this persistent itch around my vagina area, and sometimes the itch occurs just slightly into the vagina, and there IS this white discharge that looks like cottage/ricotta cheese but I'm not sure what it smells like.

I've read up on symptoms and kind of narrowed it down to yeast infection, but I can't be sure.

I'm lesbian, and I'm afraid it will spread to my girlfriend, is it possible?
I've made sure we haven't had sex after I found out about the discharge.

Also, I'm only 16 and I don't dare to tell my mom or girlfriend about it. or visit the doc, or even what kind of doctor to visit, or what to do about it at all. I'm afraid that the longer I drag, the worse the situation will become.

It makes me feel so lost, like I don't know what I did to contract it.
I also know that it's a common infection in women, but I really do not know how to deal with it, it's ruining my mood and day after I researched on it online yesterday.

Can someone help ? :-(
