Trophies and Mementoes

I know it is quite common for men to keep a trophy from their most recent conquest but I have a different slant on the practice.
My most treasured possession is a pair of my wife's sexy silk panties that she was wearing when she finally experienced a really big cock for the first time.
Every time she goes out on a date now, I get them out and sniff them inhaling her sexy fragrance.
I have various "trophies" from many different times over the years.
Anyone else have a similar fetish?
