I work as an Electrician. I have big genetals so I sweat alot in my underwear. I like to put a massager against it with my underwear on until I get off inside them. My sweat has a very rich and sweet aroma combined with my sperm. I will usually wear a pair for a few days to enrichen the pungent musk. If you have any questions just ask. I have ziplock bags ready! lol.
