what makes girls wanna post sexy images of their selves?

some do it because they don't see the issue with wanting to show off a body they love and might be proud of, some for attention, some because the human body is "art" to them, some because of ego stroking, validation, some because they like the thrill, some because they enjoy being humiliated, etc.
the one thing i do think people should be mindful of is assuming a personw ho does, is always someone with little to no self esteem, because it's not always the case
