Well, I'm a woman, and my two favorite dive buddies were actually a husband/wife team. I liked diving with both of them together, or either of them alone. None of us were competative (which I think makes a worse buddy...diving is NOT a competative sport), all of us liked photography, and all believed in leaving everything under the water just as we found it.
We all also perferred to spend the dive looking a neat fish and coral rather to see how far, how fast, and how deep we could go in one dive, and who would surface on their last breath of air.
I know divers, both men and women, who would be bored silly with all three of us.
And m1diver...CHICKS, CHICKS come on. I've never seen any little fuzzy yellow birds dive...how DO they get into all that gear?
