Selling underwear post hysterectomy

I'm having a hysterectomy tomorrow and am looking to sell some of the underwear I'm going through and have seen a bunch of mixed recommendations on how to go about doing so (especially with shipping). I know there's a pretty big market for period underwear but am unsure how transferable that is to a hysto but I'm free bleeding regardless.

I'm mainly wearing boxers for the time being and would be able to get some more fem ones if I found client(s) but am not too confident on how to sell them as most places have a pay wallet or join/processing fees and I don't anticipate selling long term. I'm alternative, have a lot of body hairy, a full bush and have a bubble butt however I'm also not quite sure how else to market myself or where.

Any advice or client recs would be appreciated.
