There is NOTHING WRONG about a girl recording herself in a bikini and feelin herself. That is competely normal, and probably built up your confidence, don't let these people tell you that it was dumb, because it wasn't, it's completely normal. It's also normal for you to wrry about where the videos go. With them being on your phone, with your account, I doubt that anyone will want to hack into your account and post them, and as long as you delete them and not post htem, you'll be fine. And girl, TAKE AS MANY BIKINI VIDEOS AS YOU WANT!
