Sperm leakage from the vagina is very normal and to be expected when there is enough sperm that your husband is ejaculating

Sperm or ejaculate leakage from the vagina after sex is normal and is expected. Sperm leakage can actually be a good thing because it means there is enough of the ejaculate.

After semen is released into the vagina, sperm immediately separates from the remaining ejaculate and sperms begin moving into the cervix and up into the uterus for fertilization in the fallopian tubes.

Sperm moves into the tubes within minutes after ejaculation in the vagina
