Sexual arousal is a completely normal response in the body which can be resolved by sex, or masturbation. The latter is simply defined as self-stimulation of the genital organs for pleasure. This can result in the body going through a series of interlinked responses in order to reach orgasm, if that is indeed the end goal. Masturbation is very common and is thought to encourage increased awareness of the body, and it even has some health benefits. People of all ages masturbate, and for many it is often their first sexual experience.
Sexual awareness is normal. Sexual feelings are normal, and there are many ways of expressing them. If a person has a disability, it does not change any of this.
Sometimes, masturbation is like scratching an itch—the desire is just there from the getgo. Other times, you have to create that itch. Even on days when you're not desperately turned on, making time for masturbation has lots of benefits , from helping you explore your sexuality to relieving stress and even improving your health.
