So true! The ring counter for the penis counts the number of calories consumed (interesting statistics for health benefits and always a good idea if used as an excuse to have a nice time).
The number of thrusts and amount of time on the job are indicators which allow for multiple combinations according to whatever you value most positively. Whatever you use it for, this black-coloured ring is simple yet effective, and perhaps this is the most attractive aspect, above all for men.
Allow us to give a piece of advice to the ladies; making sure the numbers add up and above all comparing results with the your man by your side could cause a drop in their ego from which they may never recover. Therefore, positive data only.
