Need advice

Hello guys.I need your advice.I have read a lot of articles about the fact that if man will have anal sex more than 2-3 times per month he will have hemorrhoids and prolapse of the rectum. Is it true? If yes what about gay pornstars. I suppose they have more than 3 times per day. Do you know any methods to prevent these problems? Sorry for my English. Thanks anyway. It's very important for me.
