There is quite a lot of controversy surrounding sexual practices and enabling conception.
It’s a good idea to encourage the female orgasm to assist with conception attempts. This is basically as the female orgasm causes muscular spasm of the cervix, which helps to draw the semen deeper into the cervix and thus assists in sperm travel.
The ideal scenario is that the female orgasm should occur after male ejaculation. However, remember that the most important strategy to support conception is to focus on love-making and not baby-making. Remember, lots of sex makes babies so don’t get too carried away with the details!
