Sniffing dirty undies
I am curious about one of my wife's behaviors: She keeps a pair of soiled mens underwear (not mine!)in her nightstand wrapped tightly in a baggie. On a regular basis she takes them out to sniff them while masturbating! I know she loves the smell and I am aware that she does it even though she is unaware that I know (I check on them periodically) She does this about once a week. Why would a woman want to do this? Should I be worried?
