I (20 NB AMAB)(they/them) am having my 21st birthday tomorrow and decided to book an appointment at a massage parlor that specializes in happy endings. However, i am looking to have the masseuse finger and fist me in addition to the happy ending, which is a favorite activity of mine. I know this is probably crazy, but how would i go about asking for anal play? Ive never even had a regular massage tbh. Also, im aware this entire process is risky any advice is appreciated!
