Nah, If I'd tease you, you'd know you'd be gettin some but it would be later, therefore the teasing until then when that happens later on the night. By then we'd be both so worked up that it makes the actual sensations that much more intense.
So yes there is a point of teasing to make things interesting and fun but not when you get him all worked up and THEN leave without actually doing anything. That's when some girls can take the whole teasing thing too far and turn it into a negative thing.
