HELP!

So I jist got out of the shower & when i got in after a couple of minutes while i was cleaning i noticed THIS!!! I have NEVER had a rash down there & I'm so scared! It's right on the inside of my cheeks toward my anal area... what could this be? I didnt have it at all today! Ive been using summers <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> for about a month with no problems but today was my first time trying another scent. Not sure if that's part of it because wouldn't I break out everywhere? It's on both sides in the same exact place!!! Please help.
