Yes and no. What is best sex position depends on a number of factors.  First there are several questions that need to be addressed.  Is it possible that you are able to find out if you are asking the question from your individual point of you? Or are you asking the question because you and this includes your partner want mutually enjoyable sex?  Or last but not the least , are you asking the question from the point of being pregnant?  You see now, do you not, that it is simply not a question of telling you that this sex position is the best or that is better.

There are only half dozen sex positions and the great Indian classic, Kama Sutra says that there are only four sex positions and all the rest are only variations of the four. The acrobatic and ‘twisted knots’ sex positions are merely salad dressing and nothing more.

If you are very tall and heavy, and she is tiny and on the lean side, then any position that has you putting all your weight on her is not a good position.

If a Gallup poll were to be taken of all the sex therapists in the world  and they were asked which sex position is the best, you will find four positions  are mentioned by 90 % of them. They are the woman on top position, the side-by-side position, the woman on all fours and the man  entering her from behind and the woman  lying on her back with her feet held up by the man under his arms so that her lower back is raised and maximum penetration is possible.  The other common factor in all these positions is that the woman receives both clitoral and vaginal stimulation so that she can have orgasms.

The best sex position then is the one that gives both of you maximum pleasure  and if you are both adventurous then there are always variations of these four that you can try. Lots of luck to both of you!
