Sperm may be found in the "dewdrop" of the liquid that one produces when excited, but there may be sperm before he ejaculates. It has been recommended that men try to keep their ejaculation frequency as a result of just a few times weekly; however, those that have healthy sex lives who participate in intercourse (thereby ejaculate) on almost a daily basis might argue this advice to be preposterous. Also there are women who would do masturbation.
