Don't they make this product for a woman to check her man's undies?

They should!

Or do we still have to use the "dick sniffing" method?

LMAO! OK......What I mean to say is that maybe, if I didn't trust my S/O and had suspicions of his being unfaithful and lying about it to my face and I wanted to prove to him that I did indeed know he was cheating and lying about it......YES!......I would use this product (if they made it for me to use on his under-roos). I just hate accusing someone of something that I know without a doubt is true and them lying to my face anyway! I'd like the backup proof so I could say........"Ha! I'm not as stupid as you think I am"!
