I don't know why it feels weird

I've been with my boyfriend 6 months. He took my V a couple months ago.

Well Monday we had sex and the next day my vagina felt itchy. I've never felt that way so I did a vaginall wash in the shower even took a baby wipe and wiped

Still is itchy. Not painful just awkward because you can just itch your vagina in public.

I obviously didn't share a pic but literally the outside hole of my vagina is itchy like surrounding the entrance to where his dick slides in but it does not itch internally just all on the external side.

What could it be? Still itches now and it's Wednesday night!
