I draw my limit at anal...it's just not for me. It's been tried and really not pleasurable. Anything else I think is fine.

As a submissive, I will go anywhere but my hard limits (feces, animals, children, etc.) to please my partner.

I'm a pet so I will do nearly everything to please my Mistress as she likes and commands me to. Sometimes it can be uncomfortable since she does have some interests that I am not in to and her Master is not always in agreement with things that I draw the line at but otherwise it's not an issue.
I'm more than willing to try new things if she pleases- that's part of the experience; and I let her do these things to me because I know that she would never try something on me that she hasn't tried on herself first.

I'm willing to try most things to please my partner, just so long as he would do the same for me.

Thankfully my current partner and I have the same interests and kinks, so things work out well. But.. if he wanted to try something new? I'd probably try it. That being said, there are some things that I will never do.
