Question: Can you get pregnant if you’re wearing jeans and underwear?
What To Consider
If a man and woman are both wearing jeans and underwear while they are making out, then no – they are not going to become pregnant even if the man ejaculates inside his underwear and jeans. This is because sperm cannot make their way through the man’s underwear and his jeans and his partner’s underwear and jeans to get to the vagina.
Things get a little bit trickier if both people are only wearing underwear, at least in cases where women are wearing small underwear that may push to the side thereby making the vagina available to receive semen, and if the man happens to be wearing underwear – like boxers – that sometimes allow the penis to peek out of the opening.
The bottom line when considering pregnancy risk is whether semen can make it to the vaginal opening or inside the vagina. If semen can get to a woman’s vaginal opening, then there’s a risk of pregnancy. If semen and the vagina don’t reach each other even remotely, then there is no risk of pregnancy.
Women and men who are sexually active can greatly reduce their risk of pregnancy by engaging in types of sex, such as oral sex and mutual masturbation, that keep semen away from the vagina.
If you think there is any chance at all that you might get semen near the vagina, such as through dry or wet humping or intercourse, then you should consider effective methods of birth control such as condoms and/or the birth control pill, patch, shot, or ring, or an IUD or implant, among other options.
