Doesn't Lebanon have a largely Muslim population? From what I understand, it is inappropriate for Muslim men to be naked around anyone including other men. You may have a very hard time where you are, and you may be scorned for being "accidentally" naked around other men. I know there is a large Christian population in Lebanon as well. I don't know if it would be any different with them as it may also be a cultural thing since the majority of Lebanese are Muslim. Cultural attitudes tend to find thier way into smaller religious groups from the largest religious group.
