Beds, by far! They are comfortable, give you plenty of room to maneuver and spread out, and allow for great cuddling (and drifting off to sleep) afterwards.
But actually, just any-old-where. If it's something cold like a tile floor I'd rather be on my knees or feet, but beds-counters-tables-f urniture-or-mini-golf- green, wherever we happen to be will serve just fine.
Actually, a note to anybody reading this---mini golf green is another place you're better off on your knees. That's a special breed of rugburn that persisted for like 3 months. :|
I am one of those people that as long as someone is not going to just walk in and see whats gooing on i will have sex pretty much anywhere. I enjoy having sex outside, in my suburban, on a bed, on the counter, in a shower. Yeah as long as we can fit and wont get in trouble i am up for it.
