Hello can i please put my 2cent in... I read all the post and i am bothered. back when i was going through school it was exciting to beable to dive for fun and the enjoyment. Same for the ladies. it is not fair for some guys to be bashing ladies because they are on their period. what does it matter? when you plan a dive do you ask the ladies if they are on thier period? when you get in the water do you forget you even have a dive buddy? if so you should not be diving!! I do not care either way I am always aware of my area and where my buddy is just to make sure nothing happens to her anyways. I do not know and do not care if the blood thing attracts sharks. I watch over my buddy no matter what and what if it did how exciting would that be. not many divers get chased by a shark. what would you do anyways leave her for dinner... Some guys need to grow up if they think they are that big into diving join the navy. But do not ask a female based on a dive trip if she is on her period that is so lame... anyways any ladies ever need a buddy in the brooksville fl area let me know. I will dive with ya. Looking for a new buddy anyways.
