I felt like I had something down deep in my throat, and as I was about to look down in my throat I found 7 smooth bumps, they're a tad lighter in color than the rest of my tongue, and they form a V on the far back of my tongue.

they don't hurt or itch, and I don't believe i have any allergies.
i've never kissed anyone with an std, Ever. :/

what could this be, helP?
