I have seen too many nudes and lewds from my former life in electronics repairs. (I have the scars on my retinas from seeing "granny porrn" once. We've gotten to the point where we don't d\send each other nudes. (maybe a tasteful bathtub pic with LOTS of suds, but that's it)
Rule of thumb, before you send it, just imagine explaining it to YOUR MOTHER.
