COCK WHIPPING
When soft the cock is pretty robust and can take a reasonably hard whipping. Although it has a lot of pleasure receptors it has surprisingly few nerve endings that sense pain - at least a lot less than, say, the nipples. But cock whipping has a heavy symbolic side to it and can make you feel very vulnerable, which, as a bottom, is probably something you want to embrace.
Flexible implements such as a flogger or riding crop are best; a cane can be a bit heavy. Don’t use anything very thin that might cut the skin. If the cock is laid out on a flat surface to receive the strokes then they should be lighter than if it is hanging free between the slave’s spread legs.
Remove any piercing jewellery before you play as it can tear the skin.
Never have your cock whipped when it is fully or almost fully hard. The cock has two reservoirs in the shaft, each like the inner tube of the tyre. When these are full of blood and the ‘inlet’ valve is closed down your cock is inflated and erect. If you hit a hard cock you run a serious risk of bursting one or both of those reservoirs, which is dangerous, could disable future sexual function and would need surgery to fix.
Given the cock and balls are all hanging there together, but whipping the balls is much more painful than the cock, you need to discuss this with the TOP and decide if your balls are also fair game or not. Ball pain is very strong, with its own unique sensation. Most guys hate it, but a few harness the feeling, find pleasure in it and come to crave it. Only you can know which you are.
If the balls are not up for the whipping, then they should be tied back. A cord tied around the sac and then pulled up the ass crack and tied to a belt is a good means to securing the balls remain up and out of the line of fire. Alternatively, if you are shaved, you could use duct tape – fun to get off … for the TOP ;-)
