First let me tell you that you have nothing to worry about with what you described above to me. There is no way that you could have impregnated her. Let me help you understand why.

First, you said that you are both virgins. That means that you have not placed an uncovered penis into her vagina and ejaculated. That is just about the only way to create a pregnancy.

The other ways, other than with artificial insemination for couples who are struggling with fertility, is the ejaculation at the opening into the vagina where sperm MIGHT find its way into the vagina and move up the reproductive track. I say MIGHT because this just doesn't happen easily.

Sperm are very fragile. I know they are made out to be these powerful swimmers but they are not. They need semen, the whitish protective fluid, and they need to be placed inside the woman.

You said that you did not ejaculate. That means that you didn't have sperm present anyway. Yes, you found a wet spot but that wet spot was what we call pre-cum. It comes out during sexual arousal and its sole purpose is to lubricate and clean out your urethra so that sperm that comes later will not be killed by the acids left behind by urination. There is NOT any sperm in pre-cum unless you JUST ejaculated and had a few left in the urethra that the pre-cum could bring down. I know lots of people try to make us believe that there is sperm in all fluids from the male, but research into those fluids have shown us that that is not so.

As for the small amount of blood in her panty liner, it is very possible that your girlfriend was about to get her period and this was the first spotting. It is also possible that when you were touching each other some of the tiny capillaries (small blood vessels) did get rubbed a little harder and broke. This is a very common occurrence during sex play. It wouldn't even have to be from the hymen. It could be from any of the cells in the genital area. In order to get aroused we have many blood vessels feeding the genital area so it is common for there to be bleeding even when a woman is not a virgin.

As far as they nylon keeping sperm out, all cloth will. Sperm cannot swim through clothing. Even if it is present, sperm is actually very fragile. It dies quickly, has very low motility (which is why there are millions in each ejaculation) and very few sperm are able to go into the upper reproductive tract.

I hope that helps you understand that you are not at risk for pregnancy when you are sexually arousing in the way you described. That is a very good way to express pleasure with one another safely.
