Itch down there? No other symptoms?

I recently went on my first trip with my boyfriend but the most unfortunate thing happened, I got a bad itch down there. It also feels a bit inflamed but it could just be the urge to itch gets too bad.

No other symptoms (No odor, discharge, no discoloration or major redness down there)

My boyfriend even took a look for me and said it all looks normal.

I've been using cortisone and it seems to soothe it a lot! Also, when I was in the salt water it felt better for a while.

Any ideas on what the cause could be? I hate going to the doctor (don't we all) Thanks!
