A rock, preferably with a reddish color, that gives off a white residue when it is handled.
When one person would like to have coitus with another, they could give that person a Texas Sex Rock. The gift would serve as the question, "Would you like to have sex with me?" The answer would be determined by the acceptance or rejection of the rock as a gift.
J: "Would you like this Texas Sex Rock?"
C: "Yes, give it to me!"
