性交合的技巧
8
也有喜歡自己保持相當被動的女子，她們喜歡一邊仰臥一邊承載著男方的體重。對於她們來說，“傳教士體位”（男方面對女方居上位）甚至可能是最有益的。此外，如果她們以這種體位屈曲雙腿，可以使陰莖深深地插入陰道，因而增加受孕的機會。（射出的精液在臨近子宮頸形成所謂的精池，而女子只是在性交合之後保持仰臥一會兒。）此外，對許多女子來說，陰莖深深的插入本身會增加性刺激強度，因而可以自然而然地轉換至性交合的可能的體位。
最後，我們要重申，體胖或體弱者一邊側臥一邊性交合通常最為舒適。甚至，以側臥位時的後入法可能是所有性交合方法中壓迫最小的方法。自然，這種方法本身對妊娠晚期的婦女也適用。 |

Techniques of Coitus 8
There are also women who prefer to remain rather passive themselves, and who enjoy lying on their backs while carrying the weight of a man's body. For them, the "missionary position" (man on top of woman, facing her) may indeed be the most rewarding. Furthermore, if they flex their legs in this position they make it possible for the penis to penetrate very deeply into the vagina, thus increasing the chance of a pregnancy. (The ejaculated semen forms a so-called seminal pool close to the cervix, and a woman can favor fertilization simply by remaining on her back for a while after coitus.) Furthermore, the deep penetration itself may be sexually rewarding for many women, and thus they may spontaneously shift to coital positions which make this possible.
Finally, it remains to be stated that people who are obese or weak usually are most comfortable during coitus while lying on their sides. Indeed, a rear entry approach in this position may be the least stressful of all. It naturally also recommends itself to women in the later stages of pregnancy. |
