Sexual queries. To low testosterone. ?

In childhood, even before onset of my puberty, I used to have strong sexual desires...I often got attracted to lusty things in  mere 8 or 9 years of age.. I got injured my scrotal sac somewhow while playing in the field in 9 years of age...As a result,I had to undergo Orchidectomy to remove one testis.. I can remember,,my libido was still much higher than my mates after that surgery,got heavily attracted to opposite sexes and also have strong attraction to same sex mates in early teenage days. Till now, I have strong bisexual feelings to some extent(But i have matured now and dropped homosexual feelings) Special Mention:  1) I've good amount of facial hair but little chest hair,have strong erection.. My questions are 1) Is is normal to have strong libdo since so early days of childhood or its due to over thinking of any sexual matter or any psychological problem...?? 2) Does orchidectomy affect future sexual life.?? 3) Is little chest hair related to low testosterone..??
