I'm on the last day of my period and have a long cycle. Me and my boyfriend dry humped. We were both wearing two thin layers of clothing. By the end of it I could clearly see that my boyfriends precm had leaked through both his boxers and shorts causing a wet patch. I wasn't sure if there was a wet patch on me. But my clothed crotch came in contact with the wet patch. So, if there is a leak of precm does that mean only the fluid has got thru the material and not the sperm cells? Or can they travel through the small holes in the clothing due to being very small? Is there any proof that sperm cells can't get through clothes? Please help me :(
