I was teasing my #1 dive buddy the other day about his "harem". It seems as though all of his buddies are female. He told me he just plain prefers diving with women -- they move slower, spend more time searching for little stuff, and are just basically more fun for him.
I haven't run into much attitude about women in diving, but I've had one or two funny experiences. Last year, four of us went down to MX to cave dive for a week. At one of the sites, a guide, who appeared to be local, came up to us and asked us, "Are you guys diving?" (I felt like saying, "No, we just like to haul these doubles around for strength training.") "Are you going in the CAVE?" "Do you have anyone else WITH YOU?" It was clear that the concept of four women cave diving without a nice, strong man to take care of us and keep us safe was just not computing for this guy. I let him carry my doubles to the car for me, so he felt better
And we got a few comments from the Ginnie Springs management on Monday, when three of us checked in to cave dive. They weren't unpleasant comments, just an acknowledgment that all-girl cave diving teams aren't that common.
