It seems that these devices bring women's problem equal to men but the problem still remains for both. I was hoping that people like Gnarlydog could come up with a solution. Here is a starter idea . How about a Skeg in the centre front of the seat and when it is pulled up, it launches to your crotch, providing a passage to the water.
When you finish, you simply release the skeg. Of course, there are some risks there particularly for men if you happen to get excited during the process or a shark have a fancy on you.
Common Gnarly, you have resolved the water intake recently now it is time for your next challenge.
