I am really scared. My girl and I were dry jumping with only underwear. I ejaculated while apparently the tip of my penis was at her entrance. In reality what would be the chance she is pregnant? I am really scared so please answer my question. She is apparently 2-3 weeks after her last period and ovulating? This is really scary. I don't know if my sperm went through my underwear and through her underwear but I lay on top of her when I ejaculated. I tested it out and when I ejaculate my sperm comes seeps through my underwear
