Step 1) be brave!!!
Step 2) walk over there, and say in no uncertain terms that you will not have that kind of talk anywhere near you, and if it continues, you will talk to the coach. Tell them they are being disrespectful and immature fools, who couldn't know real love from a potato if it hit them in the eye. They can act as infantile (use that word) as they want anywhere else, but you, as a lady, will not tolerate (use that word too) such perverse and vile talk. (use that phrase while you're at it!)
sound smart and suave, and they have a higher chance of respecting you. Don't mention God or your parents, they'll just make fun of you. Don not back down, no matter what. If they do continue,carry out on your threat to go to an authority figure, such as a coach or teacher.
