I Dry Humped With My Boyfrnd He Had His Jeans

I dry humped with my boyfrnd he had his jeans and inner wear even i had my jeans and underwear on. But he ejaculated twice and the ejculated liquid got onto the surface of his jeans. I also noticed a few spots of the fluid on my jeans near the vaginal area. Are there any chances of pregnancy? I am a virgin.
