I have this exact problem. My vagina sucks up water and air, and I hate it when I get out of the bath and the water starts seeping out.
The worst part is I can't find any information on it.
Even here on this forum most people think your friend is lying.
I always thought it was normal until I looked it up and everyone was skeptical about it or had no clue that it could happen :/
I feel like such an awkward peanut XD
I don't know if it is a medical problem, or why it is so abnormal. No one can answer me and it's really frustrating :/ I don't know if I should be worried.
