Can someone get pregnant from pre-ejaculate inside underwear and then wears it?

yes because it swims so if it is any were near the vagina it will go in.

Completely INCORRECT!

A. semen/pre-cum dies quickly outside the body.

B. Underware rides along the pelvic curve (even if you wear a thong or have a wedgie). The vagina/vaginal vault are INSIDE the pelvis itself.

C. The vagina/vaginal vault are behind both the labia majora and minora (The outer and inner parts of female genitalia). Then there is the vaginal vault (where your tampon sits) as well as the cervix (higher than where your tampon can reach).

D. The semen HAS to get PAST all of these and THRU the cervix to enter the uterine wall, find an egg AND then implant onto the side of the uterus.

E. That is why men have to EJECT millions of sperm into a woman. One of them MIGHT succeed and cause a woman to become pregnant.

All of these factors are what keeps women from getting pregnant every time they had sex. If it was THIS easy to get pregnant, women would have to quit having sex after about 5 or 6 times.

Getting pregnant from your underware is like thinking that if you put a letter in an envelope is the SAME as addressing it and putting it in the mail. One will reach it's intended destination, one will NOT.
