The good & extremely enjoyable positions for sex?

             Sexual intercourse may be performed in a wide variety of positions according to couple’s taste.,

The most common ones which I preferred were  

• The   women  lying on her back, the   man on top and facing her .
• The woman on hands and knees, the man kneeling behind her ( like dogs style or   This position i like much for sex because  here physical strain is less,  then bottom & top of both boy & girl will be engaged with performance )  as I know  most of my friends use this.
• The man on his back or sitting, the woman kneeling or squatting on top  of hih  if the with  woman face towards the man or  its reversal, if the woman faces away from him) . i follow this one  & previous alternatively.  So both of us can share the exercise. When boy gets tiredness girl can continue it with other position. and becomes extremely enjoyable
• Both partners lying on their sides, the man entering from the front ("side-by-side position")                                   )
