Doggy is the best, tried the rest. I can last as long or even longer than he can if its doggy, and I want him in me for as long as I can. Also want him in me more than once, this seems to be the best for him also.
On my stomach, ass up in the air, classic doggy. And I use my hands to pull open my ass for the deepest penetration.
And in a group setting, this invites multiple tops to join. Hot!!!
