Here's the basic thing. The longer and closer the sperm can get to the egg, the higher rate of conceiving. Simple right? Now let's see what are the positions that are good to make this happen.
♥ The Missionary (Man on Top)
This position is said to be the best position for getting pregnant. Why? Because this position allows the deepest possible penetration.
♥ Raise the hips
Elevating the hips as in placing a pillow behind your darling female partner. This is because this exposes the female cervix to as much semen as the male can release. Pretty smart huh?
Doggy style is also a recommended position for sperm is deposited closest to the cervix while you're doing the hump-hump thingy.
♥ Side by side
Or should I say the scissor style? I think this applies to both frontal and errr...behind interaction. xD
This has nothing to do with the positions like the above, I know. But, according to studies, female orgasm leads to contractions (which naturally, automatically occurs) that could push the sperm up into the cervix.
Get the ideas? Understand? Good. Go give your lady a good massage right now and enjoy. xD
