I spent a few months with a friend in Boston who tried to sell her used panties, stockings and lingerie. She was on Sofia Gray and was overwhelmed with messages but all of them were scammers or just wasted her time. The scammers pretended to be sugar daddy’s then wanted to switch to Telegram, Kik, Snapchat. She found a page to look at buyers who were recently online, recently spent money, spent the most money but that didn’t really help.
She tried Sniffr and PantyDeal but the situation was still the same. If she did sell some then getting the money was usually difficult. Some were crypto scams because they said they would payment through that platform. Tbh it seemed a waste of time. There are plenty of horny rich guys in the US so you should have a great time.
