Yes !!!
The wife is not a huge fan. Usually just limited to licking and fingering. On occasion with enough libations and lube will she ever let me do anal on her.
I, on the other hand am an anal addict. I started experimenting when I was very young and I’ve grown to love it over the years. Now I cannot get enough fingers, toys, or objects in my butt. I recently talked her into fisting me for the first time and oh my goodness what an experience.
Yes! My preference is my pussy but I do let guys fuck my ass if they want. Lubricant is needed, particularly for bigger cocks. I don't think I have ever orgasmed purely from anal sex but being ass fucked while I stimulate my clit with fingers or a vibrator gets me off very quickly.
