The notion that masturbation is an immature activity or a second-rate substitute for partner sex has a powerful hold on the popular imagination. Apparently, the pure self-interest implicit in masturbation makes many people uncomfortable. Countless sex manuals acknowledge the universal practice of masturbation, but it is often presented as a useful tool in the building of a better sex life, rather than as a pleasurable end in itself. It's certainly true that masturbation provides valuable information about an individual's sexual responses and preferences, and this information can enhance sex with a partner. However, we question the notion that masturbation is, at best, a necessary means to the exalted end of better partner sex.
Sex is only good if it involves two loving people.
The philosophy that motivates us is that sexual pleasure, whether arrived at alone or in a crowded room, is a perfectly valid end in itself. After all, it's delightful to take a bath alone, eat a good meal alone, go for a bike ride alone or listen to music alone. It's equally delightful to have sex alone. We like to think that there's not a person alive whose life wouldn't be greatly enhanced by masturbation. That about sums up our feelings regarding masturbation and addiction.
