Re: question on anal
Nah, you're fine. It can hurt you if you use things that are too big or pointy or jagged, so as long as you're not using a baseball bat with teeth, you should be okay. On the other hand, it is still easy to hurt yourself -- anal tissue tears easily, so don't be too vigorous or tilt anything at a great angle. Also, anything more than about an inch in diameter is not fun -- not only will it hurt but how would you like to not be able to hold in your shit?
You're okay, just be careful. They probably didn't recommend it because they just didn't like it, which is also okay.
