The chat room becomes very sexually charged as everyone talks dirty.
It's also a less intimidating way to get to meet partners before jumping into a one-to-one private chat.
For some it's just talking dirty to someone from behind the safety of your keyboard.
For others it involves dirty voice calls which can lead to climax.
While there are really no strict rules when it comes to adult chat, My Sex Hookups strongly recommends that it's always better to be safe than sorry.
