too be worried?

So just curious if I should be worried. Occasionally after I use my sex toy I don't quite smell the same down there. It's nothing too bad, I do work out a lot (but am always shower/cleaning).
But wondering if a slight odor is still healthy or when it's gotten too far? 
Ugh. Feels so strange to ask, obvi if it was really bad id know something was up, but it's just ...different... I'd say.
