Do ratchet things happen at the music festivals?

My boyfriend told me that him, his cousin and his best friend are going to the ultra music festival in March 2014 in Miami. Do people act wild and nasty at the music festivals? I've heard that the Essences Music Festival for example is called aka the sex festival. Supposedly people go with their friends to have a good time and mess with people from out of town. Is it really like that at the music festivals? Hearing that made me concern when my boyfriend told me he was going with his guy friends.
