Self-stimulation, also known as self-pleasure or masturbation, has been a controversial topic for a long time. Often considered a taboo subject in many cultures, people tend to use euphemisms to discuss this topic. There are endless synonyms for self-stimulation, including solo sex, self-pleasure, personal play, self-love, and self-touching. Some other less common synonyms include self-gratification, autoeroticism, and solitary stimulation. However, no matter what it's called, self-stimulation is a perfectly natural and healthy form of sexual expression that can lead to physical and emotional benefits, such as stress relief and increased self-awareness.
