Don't take this the wrong way, butt

Anything done wrong is uncomfortable, and or would be something you don't want to do again.
Anal play can be great, is just a question of being comfortable with it, starting slowly, and exploring what you like...
Some girls like it, some girls hate it, some girls Love it. Guys too...
Now, if the first time someone touched my ass it was done wrong, I would think it was uncomfortable too. In fact my first experiments with that area were a little uncertain, but with a little TLC, Trust me...
Done right it can be just the thing to push you or your partner well past the point of no return...
