Kolya is using his sexual experience here as a way to underhandedly exert a degree of power over Lev. Lev is at the mercy of Kolya's "teaching" since he doesn't have his own experiences to draw from. Again, this building up of Lev's lack of experience creates the expectation for the reader that Lev is going to at some point get to experience sex during the novel.
