Dear danceluver600,

Pregnancy can happen when ejaculate or pre-ejaculate gets in the vagina or on the vulva. Usually, this happens from unprotected vaginal intercourse.

It may also happen if partners have another kind of sex play that puts ejaculate or pre-ejaculate in contact with the vagina or vulva — for example, if partners have ejaculate or pre-ejaculate on their hands and they touch the vagina or vulva.

Ejaculate is produced by the prostate gland and the seminal vesicles.  It contains sperm that is produced by the testes.  Pre-ejaculate, which leaks from the penis before ejaculation, is produced by the Cowper’s glands.  It does not contain sperm that cause pregnancy. However, as it moves through the urethra, it can pick up sperm from a previous ejaculation, which might cause pregnancy.

So, it’s best to keep both ejaculate and pre-ejaculate away from the vagina and vulva to prevent pregnancy.
