So far, SNW has, that I can recall, depicting Spock; T'Pring; the waiter at the restaurant where T'Pring proposed to Spock; a number of T'Pring's subordinates at her job; a number of incarcerated Vulcans undergoing rehabilitation; the V'tosh ka'tur whom Spock apprehended while in T'Pring's body; Stonn; and Sybok.
Of these Vulcans, we only have information about the sex lives of Spock, T'Pring, and Sybok. Spock and T'Pring appear to be in a committed monogamous relationship and are engaged to marry, and we know that they regularly engage in sexual intimacy. We have also learned that Sybok was apparently in a relationship with Angel, implying that they were likely sexually intimate at least once.
