itchy?

So I really need so help/advice guys. Not sure if I should be worried or not. I started to notice an itch down there and it doesn't itch all the time but mostly when I got to wipe after I pee. There's no change in discharge or smell so I don't thinks a yeast infection. And I also just finished a round of antibiotics and steroids from being sick. Maybe that could be a link? Idk. I'm worried because I've never itched down there like this. Help?
