Any NY mistress where they provide the chastity device during the session?

I am new to chastity and kink and wanted to try out a mistress who can offer a chastity device to wear during the session. I currently do not want to purchase a chastity device for myself just yet; there is some issue of storage and it getting discovered currently (nothing bad).

If that is not option, where can I buy a cock cage via cash in NY (without it being too weird/awkward)?

thank you!
