Is it normal to enjoy wearing plastic panties ?

I have enjoyed wearing plastic panties without diapers every since I was nine years old ! I'am now 56 and still get excited every time I put on a a pair of plastic panties !I have over 50 pairs of different styles & colors of cute form fitting bikini plastic panties that I love wearing !!! Also I love to be given a good spanking with a rubber razor strap while I'am wearing them .....boy scotty
