My girlfriend and I have never engaged in sexual intercourse before, however, we have had dry sex many times. Basically, it's just the grinding of our genitals together through our underwear. A few times my penis has actually been out of my boxers, but we've never had "dry sex" naked. She has never taken off her
panties. The problem is, she is two weeks late, and we are very scared, as I'm only 16 and she is 15. I was never really worried about dry sex because I thought that the sperm from pre-cum (I've never actually ejaculated during dry sex) required a 98.6F environment to survive in. I thought it would die outside the vagina, without actual penetration. Do you think I should be worried? Is it her age and emotions and being scared about this causing her cycle to fluctuate? She has said she has never been this late before. Can anyone please help me?
