Can wearing thongs a lot cause irritation down there?

Yeah

yes!!!

Can for some people

Especially if you have the wrong size

I would have to wear thongs for dance and I wouldn’t get irritated. I agree that it’s a matter of sizing.

I imagine it could. I’ve never had a thong on for more than 2 minutes because I can’t stand how it feels!

Haven’t worn one in a while and this weekend I only wore thongs, man, I am pretty sore
