Ok, I'm going to warn you, this post is going to get into TMI territory somewhat, so read further at your own risk.
Ok, I'm fat.
My thighs touch each other when I walk.
More like rub each other.
And each summer, when it would be sweltering outside, and I left the house, my legs would rub each other, damp, and get raw. (Also when during non summer times when there were times of the month with more dampness, if you catch my drift.)
Red and painful.
Whatever you call it, it would be painful to walk, because walking would make my raw legs rub against each other, making them more and more raw with each step.
So I'd end up doing this sort of waddle, doing anything I could to stop my legs from rubbing each other.
And then each night shower, scrub very well, because then sleeping would give my legs a fresh start, so in the morning I'd start from zero when I left the house, instead of partially raw and chafed to start the day, which would happen without a nightly shower.
