This is the normal physiological response in men post-orgasm and it signals the start of the refractory period during which it's not possible for him to have further orgasms. At the point of ejaculation, oxytocin and prolactin are produced by the body. Prolactin suppresses dopamine which is key in sexual desire, hence the rapid loss of feelings of desire.
