Also, don't trust anyone who isn't asking for vetting, seems backwards but sting ops will usually skip that part while legit SWers will often demand it to make sure they're not exposing themselves to a sting on your end.
Where I am, SWers are decriminalized, but buying their services isn't. So they don't need to be afraid of stings. Not sure if that affects what you're saying.
Anyway this is all hypothetical since I have a gf right now, but I've spent most of my adult life single and lonely and would have loved to be able to access SW services safely and legitimately during those times.
