Definition - What does Flogger mean?
A flogger is a device used to flog, or whip, a partner or lover, usually during a BDSM scene. Floggers are usually made from several tails attached to a rigid handle. The tails may be made from a number of materials, including horsehair, rubber or leather.
In BDSM, the aim isn't to harm but to use pain to increase sensation, and therefore sexual pleasure.
Kinkly explains Flogger
Flogging is something of an art. When flogging someone, the flogger should start out slowly and softly, and take cues from his or her partner. Establishing a safe word is important during a flogging scene;the traffic light code - green for continue, yellow to slow down and red to stop - is very common.
