E = Experience (How experienced are they? Do they know what they’re doing?)
He knows what he’s doing, but he hasn’t done much. He’s very… deliberate in taking that step with someone, so it doesn’t happen often. 
S = Stamina (How many rounds can they go for, how long do they last…)
His average is two rounds, but he has been known to go for more (sometimes much more). He lasts a relatively long time, not so long that his partner is begging him to get a move on, but long enough that his partners are fairly impressed. 
U = Unfair (how much they like to tease)
Not too much; he doesn’t have to really delay anyone finishing so it’s not really necessary anyway. Though he does like to get his partner nice and worked up before they really get down to it.
