I'm the type who helps people, not a specific gender. I hold doors for anyone who follows me (man, woman or child)... and rarely get thanked by any of them. Courtesy should be extended to all. When I'm diving with a woman (or a man), I do not offer to help unless I am asked to. I do check their gear configuration FMI (for my information) since it could be critical in the event of an emergency. My main focus when diving with others is to offer them as much information as I can/as they desire about the marine life to enhance the diving experience.
