Ear, Nose and Throat Disorders Question

Hi, welcome to the ehealth forum and I am glad to help you.
You seem concerned by the female like voice despite being a male of 22 years.
The human voice is in a constant state of change and development just as the whole body is in a state of constant change. A human voice will alter as a person gets older moving from immaturity to maturity to a peak period of prime singing and then ultimately into a declining period. The vocal range and timbre of children's voices does not have the variety that adults' voices have. Both boys and girls prior to puberty have an equivalent vocal range and timbre. The reason for this is that both groups have a similar laryngeal size and height and a similar vocal cord structure. With the onset of puberty, both men and women's voices alter as the vocal ligaments become more defined and the laryngeal cartilages harden. The laryngeal structure of both voices change but more so in men. The height of the male larynx becomes much longer than in women. The size and development of adult lungs also changes what the voice is physically capable of doing. From the onset of puberty to approximately age 22, the human voice is in an in-between phase where it is not quite a child's voice nor an adult one yet. This is not to suggest that the voice stops changing at that age. Different singers will reach adult development earlier or later than others.
Under the influence of androgens, the voice box, or larynx, grows in both sexes. This growth is far more prominent in boys, causing the male voice to drop and deepen and in your case it is pertinent to rule out any state of androgen deficiency esp. Klinefelter Syndrome. You must consult your personal physician to rule out any disorder of androgen deficiency that might be the cause of high pitched voice and perhaps other associated features of delayed puberty that can be revealed by detailed history and examination only and the same is not possible online.
Hope this helps. Take care.
