Questions about Anal ?

Ok so I'm interested in trying anal with my partner, I have always wanted to try it out, but I'm petrified to hurt myself or experience some side effects.

I have a number of questions and I would really appreciate if someone could tell me about their experience.

There is no need to answer them all, if you could even answer one I would be very grateful.

1.Did it hurt (any blood involved) ?

2. Was it messy?

3. How did you prepare ?

4. Weird question to ask but did it get loose ?

5. Does it impact they way you've been pooping since you started it ?

6. I have some horror stories like anal prolapse, did you have any health related side effects from doing anal ?

7. Any other tips or advices to make the experience good?

Thank you so much in advance ❤️
