I think the word PREFER is what a lot of people are missing.
I think most of us would like both, i certainly would but I'm almost certainly going to PREFER one thing more that the other, like most things in life.
Ive never actually had a cock up my ass but ive experimented with toys as well and liked it.
Take girls for instance, Ive had my cock in a couple of girls arses (though not very far up) and ive liked it but i PREFER a pussy to an ass hole, it just feels softer and wetter and nicer to me.
So when i come to actually having a cock in my ass and putting a cock in someones ass i really belive i would PREFFER one more that the other.
Mabey i will like to be the one who dose the penetrating, i dont think so but I'm not sure until i try it.
Anyway what I'm trying to say is yes i would LIKE both please but i will almost certainly would PREFER one more that the other.
Ive waffled on a bit about prefer, sorry
