My boyfriend and I are still virgins and we have dry sex (dry hump) a lot but I never do it in my underwear, I always have pants on, and so does he but they're all spandex, sometimes he wears jeans. Anyway, he cums but he claims it always goes to the side. Also, 9 our of 10 times I have pantie liners on. He says there's no way sperm can go through all those fabric layers. But I worry. ALSO, we shower sometimes together and he cummed when I gave him a hand job, later his penis glided on the outside of my vajina. I've always had a fear of pregnancy and I still worry about if the slipped inside me. I never track my period and I'm on it, but I've had horrible cramps that I usually never get with my period and I feel sleepy and if I think of it, I get terrified. And my boyfriend is really getting annoyed with me because he says sperm can't survive that long in the air and the water washes it away. But I really don't understand, I'm scared. Am I just paranoid? Or is it possible?
