Can sperm pass through pantyliner?

[Len]

Hi, I would like to ask if sperm could pass through pantyliner because yesterday, my girlfriend and I dry humped (me on the bottom and her on top of me), I was fully naked and she's wearing shorts with her underwear with pantyliner because her ovulation will start today which already happened because there's a clear discharge and her libido is high. Also I didn't ejaculate, only precum was involved. I just want to clarify if the sperm could pass through pantyliner.

FYI - We did dry humped again during her ovulation but I was fully clothes (shorts and underwear) and she's wearing jeans and her underwear with pantyliner so 4 layers of clothing so I'm thinking that didn't cause any pregnancy risk. Also I didn't ejaculate, only precum was involved.

Hi there.

This isn't at all how human reproduction works. Why don't you start by taking some time to read through this explanation of how it actually happens -- including what is needed, like a lack of these kinds of barriers: Human Reproduction: A Seafarer's Guide.

If there's anything in there that doesn't quite make sense to you, or you'd like explained in a different way, I'm happy to circle back.
