Help!

Was fingered last night. Today was feeling uncomfortable in underwear down there, just assumed it was from shaving, however decided to take a look just now because it was quite painful, and there is a small bump!

Not white, (normal colour as the rest of me) but pea shaped. No blood or pus. Slightly concerned as it was my second time being fingered…

Should i be worried? As much as I know i shouldn’t be, i am kinda scared to go to doctor and hoping its something that will just clear by itself...

Thanks!
