No. Clean pain sounds like taking a hot shower where maybe I get really sweaty and it feels steamy and sweltering, but I know I'll be clean at the end and people will be happy that I smell good. Dirty pain sounds like doing a striptease where I get really sweaty and that feels really dirty and naughty, but I know I'm using my vulnerability to make people happy. That's just what "clean pain" and "dirty pain" sound like to me, but they probably mean something else.
