Sexual role-play is when people act out characters or scenarios which may sexually stimulate each other. This can include fantasies (discussed above) and fetishes, such as BDSM (bondage and discipline, dominance and submission, sadism and masochism) or age-play. It has been described by some as an adult form of L.A.R.P (live action role-play).[14] Role-play can also be carried out online, by typing stories to each other or pretending to be a character, and is therefore a form of mental stimulation you can engage in with another person without them being physically present.
