The credibility of a complainant of an offense under this chapter shall be determined by the same standard as is the credibility of a complainant of any other crime. The testimony of a complainant need not be corroborated in prosecutions under this chapter. No instructions shall be given cautioning the jury to view the complainant's testimony in any other way than that in which all complainants' testimony is viewed.
