This character engages in sexual activity done in discreet from third-person audience(s) unaware of the act. e.g. caressing partner's genitals under the table, sex where one of the participant is invisible, etc.

Unlike exhibitionism which draws sexual pleasure by exposing the act to an audience, discreet sex focuses on doing the sexual act publicly but discreetly where the audience knows nothing of what really is going on.

Note: See Sex in front of an Audience for when the audience is fully aware of the act.
