Role-playing means impersonating someone. You can be a boss, she’s your secretary. You can be a pilot, she’s a stewardess. Take and wear any role you feel fits you. The main thing about this – is to arouse the desire, make it burn somewhere it was not burning before. Also, it is a possibility to investigate a body of your partner in something new (a costume or special lingerie) and to put something on yourself. You can be a tiger, a dog, a man, a woman. Yes, changing roles in sexes with your partner sometimes arouses very much – much bigger than toys or outfits. Also, you vastly use your imagination – to make the process sparkle with colors.
