The dominant side of the bed!

I have just been reading an article referring to the above and it states that:

Looking from the bottom of the bed the LEFT side of the bed is generally the dominant side this is defined by the fact that most men are right handed and this gives him natural access to his partner.

Would you agree or not with this statement?

Love and Licks .. Tiff

ps I also read somewhere that in medieval times it was also to give the knight easy access to his sword
