  Our Philosophy sex is like dancing, it changes every time. It depends on culture, atmosphere and mood. Sometimes it is done alone, with a partner or in a group. It can be fast and hard or slow and soft. Sex is a combination of non-verbal negotiation and verbal cues: a scream, a twitch of the toes, or a flush of the face. There is no one 'right' way to move, only what feels good to all those involved.
