Re: Sex Question
No. Bottom line - If the cum gets in the girl, there's a chance she'll get pregnant.
A women's orgasm both sucks up the semen (to make it easier to get pregnant) and shows that the man is a fit enough sex partner to have her reach orgasm and bring her that much pleasure, making him a good mate.
But no, both partners climaxing at the same time is not a requirement for getting pregnant. There's even a slim chance to get pregnant if the guy pulls out before he reaches orgasm.
