Is Anal sex is dangerous?!

Hi

I’ve tried anal sex about 4 times. I really enjoyed. I never had vaginal sex and I don’t want it until marriage so the only way that i can have is anal. I worry about it so much . I think it’s so bad and have many bad effect on my body and I don’t want to loose my control on pooping or S.T like this . But also i was search the web and i realized this is not as bad as the people think.

What do you think? Do you have any experience that can share with me?

Is it not dangerous as I think?

And the next question i have is I tried it 4times. Is it already effect on my body? That means my anus can get back to what it was be?

Thank you to helping me and advice me
