Yep.

I am a big proponent of humans of any gender(s) (and agender humans!) masturbating in ***appropriate*** situations. This is not an appropriate situation.

Appropriate situations for someone else to be able to hear someone else masturbating:

a) a partner or casual hookup who has consented

b) a sex party where everyone around consents

c) a sex worker/client interaction with consent

d) a phone sex operator/phone sex client with consent

e) a porn film shoot with consent

f) a sex therapist/sexual surrogate with consent

g) if you work at a fertility clinic, and send a patient into a room with a cup and a magazine to get a sperm sample, it is not unreasonable that you might possibly hear some sounds coming out of that room (altho a clinic should probably look into a white noise machine or sound insulation)

a random workplace, where the product/service being produced/provided is not sex or sex related, no!
