no real interest in sex

hi.........

I am 22yrs old male.i have no real interest in sex. I feel that my sexua| desire has decreased gradually since I was 16.

I am not aroused visually by either men or women, and I seem to only be able to attain an erection through actual physical stimulation of the penis, which seems not to be very sensitive anyway. Occasionally I can get an erection through physical contact with a woman, but it is not a strong erection and usually doesn't last very long without physical stimulation. Even in this situation it seems more of a reaction rather than an actual desire.

This has given me problems relating to other males in my age, and it makes relationships with females complicated.

I have not heard much of a problem with a lack of sex drive among males my age. Please tell me where I can find more information about this, what the problem could be, and what I should do.
