Gay sniffing underwear

I have a gay best friend that came to visit for the weekend and my boyfriends brother confessed to me that he sniffed my friends boxers. He snuck upstairs while we were all hanging out and creeped into my friends room and found a pair of his underwear and stuck his nose in it.
I recently wore one of my jocks twice without washing it and sweating from working out and using the sauna really did it’s work and seasoned the pouch. Sniffing it is like taking a natural viagra supplement for me. How long do you all season the pouch for? Also if anyones in the DFW, TX area, I’m down to trade.
