Kamasutra or Kama Sutra by Vatsyayana is a book that extensively deals with reaching woman or female orgasm as well as complete male physical satisfaction. Thus this book has established itself as a must read for both men and women equally.
Well, yet another erotica!
… and for adult only!
Some women may readily reach climaxes, but for others, having climaxes through sex calls for some sexual knowledge. Even the top sex position will not ensure orgasms through penetration without other excitement. It definitely could be done if you’re wanting the lady to get climax quickly.
