One thing I find strange, and Lina is an example, is that some of the women will show all when bathing or having sex...but will turn their back to the cam when changing their shirt. Even Lora does this most of the time.
Maybe i can answer that JoJo... When the girls have sex they don't think about the cams so they have no problem to show all the naked body.
Here in spain and mostly of europe the girls like to do topless, i see my friends tits all summers in the beach but when they change clothes in the house they are pretty careful of show nothing.
Maybe for you guys in america it's peculiar like to us it's weird than you can show blood, death and thing like that in tv when you make movies but you can't see tits or naked bodys on tv. (like janet jackson nipple in the superbowl, after that all the events aren't live, you have a 10 seconds delay to prevent that LMAO)
And about the showers, depends on each person, i take a shower 2 times every days at morning and before sleep. In summer 3 times.
