The word cum comes from come which was sometimes used to describe ejaculation or semen. I think it's time we officially incorporated the word cum, and its past and past participle cummed into English language so that we don't confuse it with the original word come which already has enough definitions of its own. It won't lose its charm with one less definition. You'll always want your sweatheart, love of your life to come to your bed and cum along with you.
