Re: Area between vagina and bottom
I get this too. It's as though that area gets 'rubbed', particularly in certain sexual positions or when having sex a bit longer than normal.
I haven't bothered going to a doctor as it heals on it's own. Helps to be careful with certain positions.
Carmex ointment is another good thing to apply. It's a clear gel-like cream, normally used for cold sores or for chapped lips. It's very cooling and appears to clear it up much faster.
