No kidding! My boyfriend never ejaculated inside me, and after less than two months of lots of unprotected sex, I became pregnant. Oops!! As I now know, sperm IS present in pre-ejaculate. So when they told us in sex ed how the withdrawal method doesn't work? Believe it!
On a side note, now that I am pregnant, my boyfriend ejaculates inside me all he wants, which makes our lovemaking all the better.
