They were both written in India in Sanskrit about the same time and have the same word in the title.
Kamasutra gives different methods for love making(sensual pleasures ).These different methods are in the form of asanas.
‘Kama’ means ‘desire’ not sex. In Kamasutra there are so many chapters which include satisfaction of desire and chapters about other desires, like how to make money, how to get power and position in society etc. However these chapters are normally not included in the books one finds in the market on Kamasutra.What I feel this desires of love making refers to sex only and kamasutra is sex manual created by Vastyan and its purpose is to satisfy and happiness of couples.
yoga is really about creating balance in the body through developing both strength and flexibility.
