Me and my SO where having sex with a condom yesterday for quite a while and at some point I noticed that there was some precum inside the tip of the condom, I didn't think much of it. But after a while we switched positions where she was on top. When I finished I pulled out but I noticed some curdy white liquid inside the condom at the base when I took the condom off. My thought was that as I took the condom off my penis could've pulled some semen from the tip towards the base of the condom, but I'm not sure. My question is, do you think the precum could've been forced down the shaft when she was on top? and if so could the ejaculate travel all they way up her birth canal?
