Anal 😬 & rim jobs

Hope everyone is having a greag day.

So me and my partner would like to try anal. However I'm a bit shy about it in regards to the mess.

I've tried anal beads in the shower alone, and I always have a mess left on the beads. Is this something that will eventually go away.

How do you guys deal with this. The only thing I know about anal is what I see in porn. However, I never see a mess on the mans penis in the video and the girl or guy will do ass to mouth. Are they not tasting 💩?

I just fear I'll have poop all over his penis or when i finger his but I'll have it on my hand and bed and its going to be a whole gross mess. 🤦🏾‍♀️🤦🏾‍♀️ 🤢

Also when do a rim job/eat ass... does it taste like poop ( don't even know if poop has a taste) is the smell not unbearable?

Any advice?
