Big Problem!

Okay this is my first post on here so I hope nobody is too judgmental on here. I’m just going to go for it.

So my sex friend and I have been having sex with each other for about a year now, and for everyone out there that says that friends with benefits relationships don’t work you are wrong you just haven’t found the right friend!

Anyway he keeps telling me he wants to try anal... he has already done this with another girl so he knows what he is doing but I got no idea!!! Help!!!!

I am honestly kinda scared about how this could go and he keeps bringing it up and I don’t know what to do! Like none of my friends would ever do it so I can’t like talk to them about it cause they would think I am disgusting for this but I am actually like thinking about it... like I mean you only live once and it wouldn’t be the worst thing to try right? I don’t know I need some opinions and some tips! Please!!!
