on hinge for the first time in 12 yrs and i genuinely dont know how much of my past to share

so im back on the apps after my marriage ended and im completely lost on the question of... when/if/how do you tell a vanilla date that you spent the last decade in the lifestyle. like its a huge part of who i am and what shaped me. but obviously not first date material. do i wait til it's serious? do i never mention it? do i look for fellow ex-LS or current LS ppl specifically? feels dishonest to hide it but also feels insane to lead with it. im 39 from glasgow if context helps... what worked for you
