Anal ? Help!!!

Hi. This is my first post . Lol so my boyfriend wants to try anal and I’m willing to because it’s for him and he even got tips from his dad... but i don’t have any ... so I’m coming to who I consider my tribe lol. I’m a Virgin when it comes to this hole and I don’t want to be caught too much off guard. I’m not really into douching I know it’s not good for you in the long run but at the same time i don’t know enough about anal besides what i see on porn which is pretty unrealistic... any help would definitely help and be appreciated.
