Of course I listen. Thats how I know the first rule of anal sex is to use lube.
The second rule is to use more lube.
Then assuming you want to engage in anal sex more than once with your partner, you use plenty of lube and work your way upto penetration by slowly stretching the orifice with a finger, then two, and gradually using larger toys until the anal receiver is comfortable with something of approximate size to your penis.
Continue with this train of thought and eventually you could work your way upto anal fisting, but thats another topic for another thread for another day.
