Glass plugs are rigid and offer firmer, heavier stimulation. They are temperature sensitive, so they can be heated or cooled to add sensations of hot and cold.
Just follow these steps!
1º Cover the plug with plenty of lubricant and place yourself in a comfortable position.
2º Place the tip of the plug against the ass and push it inside. As the plug enters, it will pass through the super sensitive external muscle and that might already give you some pleasure.
3º As it goes in, the plug will find the internal muscle. Give it time and remember that a little discomfort is normal, but if you feel any pain it's important to stop.
4º When the plug is in place, you should feel a sensation of fullness. You can feel the plug against your P-spot or prostate.
5º You can gently tighten and relax the muscles and alternately, moving the body for an internal massage without hands.
6º If you climaxed while using the plug, the muscles in that area have just contracted. That means you'll need to wait a minute or two for your muscles to relax before removing the toy.
7º Finally, you should pull gently, wash with warm water, wash your plug well and, preferably, let it air dry.
