PLEASE DO NOT RUSH! Rushing could cause injury and could scare you along with could even damage your rectum. Please use toys that has handles or even suction cups to avoid it getting loss in the butt. It can get stuck and you could possibly need to go to the hospital that would be a wicked story like why are you here? I got a toy stuck in my butt hole or its lost deep inside.
Beginner toys are prefect for this since they are made smaller to help you loosen up and stretch out. Anal lube is kind of thicker and slicker and can be stickier than the other lube. It is like this to so that you do not have to keep applying and the water will just end up drying up.
