So sperm alone not comes out.now I think you will understand the process of fertilization.

Don’t worry about what’s happening. It’s quite normal for some semen to come out of vagina after intercourse. Sperms will go in and can fertilise the ovum. Don’t get confused. You can’t have intercourse with urethra.

You can't have intercourse through urethra, so the sperm is obviously getting deposited in vagina. For other queries feel free for a consultation.

It is likely the sperm to have entered the vagina and the excess sperms is likely to have come out.
