Panties/Knickers smell

Hi all, thanks for reading. Iam writting in hope of confirmation of sanity, lol. I find the scent of my wife's knickers to turn me on. After we make love, i normally have to pass her knickers back. I have a kwik sniff before i pass them over, and soon will be taking them off again.
I have heard of (fishy) smell but this is not the same. Does anyone feel the same? or have i completly lost it?
Ted.
