OPINION
Appellant stands convicted of an infamous crime against nature, committed through oral copulation with a 14-year-old boy. See: NRS 201.190. Appellant here contends the trial *652court erred: (1) in allowing him to conduct his own defense; (2) in holding he could be convicted on the testimony of the boy alone, without corroboration; (3) in holding the “infamous crime” statute constitutional; and (4) in sentencing appellant under NRS 201.190(1) (a) rather than NRS 201.190(1)(b). We reject all contentions raised.
1. Appellant wished to conduct his own defense. In fact, he refused to go forward with any member of the public defender’s office as counsel, or to cooperate with members of that office in any manner. The judge canvassed appellant concerning his educational background and knowledge of the charge against him. He explained appellant’s right to cross-examine witnesses, his privilege against self-incrimination, and the availability of compulsory process to bring witnesses before the court. The public defender remained throughout the trial to assist in any manner requested. Before the second day of trial appellant was given another opportunity for representation by the public defender’s office and again he refused. Prior to trial, two psychiatrists examined appellant. Based on their reports and testimony, the district court determined appellant competent to stand trial, to aid in the defense with his attorney and to make any waivers that might be necessary. Under the circumstances, we cannot hold the court erred in finding appellant capable of a voluntary and intelligent waiver of his right to counsel. Cf. Hatten v. State, 83 Nev. 531, 435 P.2d 495 (1967); cf. Faretta v. California, 422 U.S. 806 (1975).
2. Appellant next argues that the complainant, a 14-year-old boy, is an accomplice and that therefore evidence corroborative of his testimony was necessary.1 NRS 201.190(1) speaks to “every person of full age who commits the infamous *653crime against nature.”2 We have previously defined “Ml age” to mean 18 years. Basurto v. State, 86 Nev. 567, 472 P.2d 339 (1970). NRS 201.190(1) is designed to protect, and not prosecute a 14-year-old. The complainant was not liable to prosecution for the identical offense and as such was not an accomplice. NRS 175.291(2); Geddes v. State, 90 Nev. 367, 526 P.2d 1180 (1974).
3. Appellant contends NRS 201.190 is unconstitutionally void for vagueness and also unconstitutional as applied to the facts of this case. The vagueness contention has been considered and rejected in the past, and we here see no reason to review this issue. Jones v. State, 85 Nev. 411, 456 P.2d 429 (1969). Concerning the statute’s application to this case, appellant argues the statute is unconstitutional when applied to “consenting adults.” This contention, which other courts have upheld, certainly has force and will be duly considered in a proper case. See, for example: State v. Elliott, 539 P.2d 207 (N.M.App. 1975). However, a 14-year-old boy is not an adult for the purposes of NRS 201.190. Basurto v. State, cited above. We have previously upheld the statute’s constitutionality in noncon-sensual cases. Jones v. State, cited above. That holding is no less applicable where the victim, because of his tender age, is incapable of effective consent.
4. Finally, appellant contends he should have been sentenced pursuant to NRS 201.190(1) (b) rather than NRS 201.190(1)(a).The statutory mandate is clear. NRS 201.-190(1) (a) provides the penalty if the “offense is committed upon the person of one who is under the age of 18 years.” Here, the victim was 14 years old; appellant was properly sentenced.
Affirmed.
