Is masturbation immoral? What does an atheist say?

My title was going to be: "Is masturbation a sin." Yes, in most religions, masturbation is a sin, but atheists do not sin. The concept of "sin" is purely religious.

I have been called various names when I openly tell my friends both religious and non-religious people that I do masturbate when the need arises. Some, if not all of my non-religious friends, said that I am insane and the act itself is disgusting. My religious counterparts said that the whole thing is immoral and sinful.

Atheists don't sin but we can break the laws of the land individually and are always available to pay the price of our actions. Masturbation is not a crime in Uganda. So am not neither breaking the law by doing it. There are religionists that say their God didn't create man or woman to pleasure him or herself! Well, the concept of a god is bogus, so I simply disregard just about everything religionists tell me. Point is, I love masturbation--just like all other men and women.

Many people have problems with religion because of masturbation. They were taught that masturbation is bad and that their god strongly disapproves of it. So when they masturbate, they fear that their powerful god is watching and will severely punish them soon or eventually. I am a normal man and I love my life, because I am not hurting myself with my desires.

Masturbation is not evil, dirty or harmful - it will not make you go blind, drive you insane, turn you in to a pervert, stunt your growth, give you an STD, make you sterile or get you pregnant. Both guys and girls masturbate; it is a normal and healthy part of sexual development.

Masturbation is a very personal thing and should not be done in public places or around people who are not willing partners (think safe sex activity). You are normal if you masturbate, normal if you wonder about it but don't do it, and normal if you never give it a second thought and don't do it - it is one of the few things in life that is "normal if you do and normal if you don't".

Masturbation may make sexual intercourse more enjoyable because you will already know what it takes to "please you". It alleviates stress and releases endorphins (the pleasure hormones) in to your system making you more relaxed. 

Masturbation as exploration of the body is common in children between the ages of 3 and 6, in teens masturbation becomes more sophisticated and sexually motivated. Masturbation is also practised by most adults of all age groups. Surveys have shown that 80% of males and 59% of females have masturbated by age 18.

Many experts believe that masturbation is more prevalent in the teen years due to a strong fluctuation of hormones; masturbation alleviates the strain of this build-up and is a necessary part of development.

The only real problems that come with masturbation are psychological and are the result of unhealthy attitudes toward doing it (if you do it, but are ashamed) or abnormal practices (for example, public masturbation).
