I'm not comfortable talking to my girlfriend about this so I'm going to tell you what I know and hope I get some helpful advice.

I apologize if the way I describe this is too visual, but I don't know how else to explain my situation.

My girlfriend's vagina has a bad smell. It's hard to describe the exact smell but it is definitely fishy, and maybe even a bit like feces.

When I insert my finger deep enough into her vagina (palm upward) and curve it forward so that it's pressuring toward her pubic bone, I can feel bumps that are kind of soft but also kind of sharp, and they feel almost like slices as I slide my finger outward pressured along her vagina wall.

She's normally dry down there, but when she's horny it can get wet enough to soak through whatever she's wearing without either of us doing anything physically. This liquid is usually clear but sometimes it has milky fluid with tiny bubbles mixed with it. When she orgasms, there's noticeably more milky fluid.

I'm pretty sure she's not experiencing any itching or burning, but sometimes following sex she can experience soreness or irritation.

I'm concerned that she has a yeast infection/thrush or some kind of other infection, or worse some kind of STI/STD.

What does this sound like (if anything) to you?

I want her to get checked by a doctor, but I don't know how to tell her. How should I bring this up?

Thanks!
