This thread annoys me, so I'm going to post for no reason. I went through all unique posts (i.e. no child posts) that had the tag at some point and counted this:

Correct Usages: 9

• ruined_orgasm (9)

Questionable usages: 9

• ambiguous scenarios (2)
• teased with negligible stimulation to orgasm (4)
• blocking semen flow during an orgasm (3)

Bltatant mis-tags: 35

• hands-free, especially in an uncomfortable position (16)
• cock_and_ball_torture (9)
• orgasm_denial (2)
• chastity (2)
• walk-in (2)
• miscellaneous sexual frustration (4)

It's been my tagging philosophy to make sure any niche fetish is tagged, but... yeah, I can't win this argument.
