Anal Stretching vs loosing ass strength

How many of you that do anal stretching cannot contain farts? Be honest.

Everywhere I am investigating it says that if toys are more than 6cm in diameter the ass tone will degrade and farts start leaking when you cough. Even if you do kegel exercises.

That makes me afraid.
Is this a consequence to accept?

Is there any "good" way to stretch?

Please advice. Real answers. Real people. Not "my ass is stronger than before" B:S. PLease answer with details. It will help eveyrone. Thank you!
