回帖是好品德。

生殖器可从正面交合，这是最普遍的一种性交方式。
        女方平躺仰卧，双膝微弯稍分开，这样可使精液射在宮颈口周围，这样的体位对子宫前位的女性最佳。如果你想怀孕，性交后，就应该老老实实地在床上躺着休息一会儿，这样可以防止精液外流。千万不要马上起来，也不要冲澡，可以等一等。
　　姿势二：是从背面进入，这样的体位对子宫后位的女性可能更佳，更有利于宫颈浸泡在精液池中。
　　所有的女性在性交后采取仰卧平躺姿势时，都会有液体从阴道中流出，并不是你的阴道容纳能力低下。为了确保受孕，性交后女性可把双腿朝空中举起，或者在臀下方塞一个枕头，使上身处于一个臀高头低的位置。再或者采取侧卧姿势，膝盖尽量向胃部弯曲，这样同样可以延长精液在阴道的存留的时间。
