Yes yes its better if you do, but take your time dont hurt your butt.
>tips ?
Do it only if you want to cause its your butt not his, take your time and tell him to take his time to, try to be clean outside like inside try to poop a few hours before , lube is your friend and use a condom if you dont know him alot.
And if you dont like it tell him to stop.
If you are new to butt play maybe starting with a real cock is not maybe the best choice, try to get a little toy before cause butt play takes time and it will hurt alot if you are not used to
