How tight should a cock ring be

Snug enough that a fingertip slides under with mild resistance. If it hurts, it is too tight. Store prices and published specs only. No disease-treatment claims

By Mammoth Force Editorial Published September 3, 2026 1 min read

Snug, not painful. A fingertip should slide under. If nothing fits under it, take it off.

Red Tiger is three rings with no published inner diameters. Try them. Do not guess millimetres.
