性交合的技巧
1
一般而言,适当地告知夫妻不要贸然而仓促开始性交合,而要从容不迫,以深思熟虑的方式逐渐展开。例如,他们可能会发现首先以某种手交或口交更为有益。以这种方式,女性在性交合之前甚至就可能享受到性高潮。至少,只有当阴道已经自然分泌足量的润滑液时才应该去尝试性交合。如果没有这种润滑,阴茎的插入对双方都能够造成疼痛。(在一些女性,仅仅随着岁月的推移,阴道自然分泌液可能就会逐渐变少。这种症状通常通过激素疗法可以得到改善。在市场上也有某种预涂润滑液的避孕套可供购买,它原来也可以改善这样的症状。不过,一些诸如凡士林这样的人造家用润滑液,可以用来进行手交,但不应该用于阴道润滑。)
一旦女方的阴道充分地润滑了,男方就可以逐渐插入阴茎。不需要立即插得很深,因为尽管女方已经性兴奋起来了,她仍可能有一阵子会感到紧张。在这种情况下,男方刚好用阴茎头在阴道外方和缓地前后滑动,通常能够有助于让女方放松。然后,当她意欲交接的时候,她可以以自己骨盆的耸动加深阴茎的插入。哺乳动物在性交中的骨盆耸动出于“自然”,而且,事实上能够在人类的婴儿中观察到这种现象,当他们开始去探索自己的性反应的时候,他们就会有骨盆的耸动动作。不过,这可能是作为本能的行为,能够极大地与富有经验的爱人的实践加以改进。 |
Basic Types of Sexual Behavior |
2. Heterosexual Intercourse: Genital Intercourse |
Coitus |
Techniques of Coitus 1 In general, couples are well advised not to begin coitus suddenly and hastily, but to take their time working up to it in a deliberate fashion. For instance, they may find it more rewarding to engage first in some kind of manual or oral intercourse. This way a woman may even enjoy one or several orgasms before coitus. At any rate, coitus should be attempted only when the vagina has produced enough of its own natural lubrication. Without such lubrication the insertion of the penis can be painful for both partners. (It is only with advancing age that the natural vaginal lubrication may become insufficient in some women. The condition can usually be improved by hormone therapy. There are also some prelubricated condoms on the market which may prove helpful in such cases. However, certain artificial household lubricants, such as Vaseline which can be used in manual intercourse, should not be introduced into the vagina.) Once the woman's vagina is sufficiently lubricated, the man can gradually insert his penis. There is no need to penetrate very deeply right away, because, in spite of her sexual excitement, the woman may still feel a little tense for a while. In this case, the man can often help her relax by slowly moving just the tip of his penis back and forth in the outer part of the vagina. Then, when she feels like it, she can deepen the penetration by her own pelvic thrusting. Pelvic thrusting during sexual intercourse comes "naturally" to all mammals and can, in fact, already be observed in human infants when they begin to discover their sexual responses. However, instinctual as this behavior may be, it can be greatly improved upon by experienced lovers. |
