Normal hormones + immaturity + insecurity + peer pressure + group beliefs. A confusing mix.

There are healthy ways to deal with sexuality, inbetween the unhealthy extremes of obsessive bragging, jealousy, aggression, or puritanical disgust (or worse yet, a mix of these). I wish everyone would just get it right already, but apparently this takes a bit of work.

People sharing nudes sent in confidence without permission are not respecting other people's boundaries / feelings. Maybe they need a refresher course in privacy and trust. I would love to ask them if they are okay with people borrowing their personal effects without permission, or having their medical information or social security number, etc. posted on a public website. If I got a "No", I'd love to discuss with them a concept called hypocrisy.
