I've organized several these in the past and they've been pretty successful so I thought I'd give it another go.
If the thought getting a complete stranger's underwear mailed to you gets you going, then this is for you! I am organizing an exchange men's underwear in which you will receive a pair underwear from a complete stranger in exchange for a pair your own underwear. If you are interested in participating, please fill out the form in the following link: https://forms.gle/wpcDoT3ab9NXveid9.
This form will be open for around the next 2 weeks or until there are a fair number people who sign up. If you sign up multiple times, I will assume that you made a mistake and are simply correcting it. No multiple entries will be allowed. If you have questions, please PM me or respond to this thread.
