Early 40's underwear loving guy.
I've always had a pa**ion for underwear (boxers, briefs, unusual fabrics like lycra, satin, mesh) and sports shorts (footie/nylon shorts a favourite). Especially another guys worn gear full of their sweet musk and a hint of pi*s drips...and obvious c*m stains an added bonus.
Nothing beats inhaling deeply on a quality pair of undies smelling and tasting the guy whilst I wank then wearing them to add my own loads to.
