Butt stuff with my butt?

Usually, I like butt stuff with man butts- so i clearly don't have an issue with anal or something, but when it comes to my butt, it's either just insanely weird, a complete turn off, or nothing really.

I've had limited experiences, I've only fingered own butt, and just felt weird both times.

I've had other people try to touch or lick it during sexy times and it immediately turns me off?

How do you like butt stuff? Maybe I just don't, but I kinda want to try to see if im missing out, lol. I am experimental.
