Hallow Dear,
The sexual excitement, hence sexual functioning of any individual starts from the intrauterine life.
After the birth, the child does have sexual feelings, only the areas of sexual excitement are different. A child of 3 years urinates in the rooms or in front of the guests. This is one of the expression of sexual satisfaction. Hence, even if you started satisfying your sexual feelings at the age of 6, it is not abnormal. So long as you have not indulged in heterosexual experiences at such an early age, it is fine.
Outlet to the sexual urge is absolutely physiological and normal lest unsatisfied sexual urge may lead to different forms of psycho-somatic problems. Pelvic congestion leading to low back ache is also one of the conditions due to unsatisfied sexual urge.
Masturbation a very safe way of letting the sexual urge have an outlet. Many individuals masturbate in their life. My dear, this is not at all a sin or guilt or bad practice so long as it is not affecting your normal way of life and thinking, and not disturbing your social relations and life.
Masturbation is a state of fantasy thoughts. Please take care that fantasy does not encroach on your normal sane thinking.
It is likely that you may loose your
hymen if you are practicing intravaginal masturbation. If you keep your hymen intact, you can practice only clitoral or labial masturbation which also give equal satisfaction. Also, please keep absolute hygiene while masturbating. You should not handle the genital organs dry lest pain and discomfort.
I hope this convinces you and takes away guilty feeling from your mind. If so, you may caste a 'Helpful vote' for me.
