Penis extenders are very easy to put on, care for and remove.
You should know that every time before you want to use a penis extender you must achieve erection first. You can have it either by using a sex toy (for instance, a penis pump) or during foreplay.
Always apply lubricant to your phallus and the inside of the penis extender. Don't use too much lube to avoid slipping of the toy during intercourse. You'd better use a water-based lubricant instead of an oil-based. The latter one can harm material and damage the sex toy.
Delicately slide the hollow device onto the penis up to its end. Make sure it snugly fits against the tip of the phallus.
Now you are ready to explore the Realm of Satisfaction.
