After the euphoric bursts of pleasure that captivate your body for some exhilarating moments subside, then it's nothing special. The road leading up to the climax is what it's all about. It helps if your partner can react to you and vice versa; it's not fun when a hyper person is stuck with a person who lays completely stiff.
If you find a special partner, like a female kirby007,- it can be hours of fun.
