Are you buying them because you want a deal on a sex toy? Or you selling them because it is someones fetish to buy them with your stink on them? I equate it with buying used/dirty panties... if a guy wants to part with his cash and give it to you....go for it. I'd sell almost anything (legal) given the chance. I used to have woman i was phone-sexing, send me their bras so I could sell them. What is the difference? Now, if you just want a deal on a used toy, I'd say gross. Not enough boiling acid in hell to disinfect them enough for me.
