Questo crescente livello è vissuto come piacere e più alto è il livello, più intenso è il piacere a condizione che vi siano recettori sufficienti per accogliere il crescente livello. Il piacere intenso dell'orgasmo che sperimentiamo è dovuto dall’improvvisa afflusso di dopamina che viene rilasciato nel centro di ricompensa del nostro cervello.
La prolattina è il neurotrasmettitore di sazietà: applica i freni, per così dire, il livello e la durata della dopamina e ossitocina. I livelli di prolattina rimangono generalmente stabili al centro di ricompensa del cervello, tranne durante l'orgasmo quando sostanzialmente varia (ad esempio per contrastare o ridurre il livello di dopamina e ossitocina). I livelli elevati di prolattina dopo l'orgasmo persistono per un minimo di una settimana e fino a due settimane.
Ossitocina: spesso chiamato "l'ormone coccola", quando il livello è elevato, esso produce la piacevole sensazione di legame o "connessione,", così come i sentimenti di vicinanza, di devozione e di protezione. È il fattore primario nello stabilire la base per legame di coppia. Una raffica di ossitocina viene prodotta durante l'orgasmo ed è responsabile per il bagliore residuo d'amore post orgasmo e la connessione che sentiamo.
Dopo l'orgasmo, negli uomini, il livello di ossitocina o scende rapidamente - in meno di un'ora, è ben al di sotto del livello a cui era prima che l'eccitazione sessuale è iniziata. Nelle donne, il livello post orgasmico di ossitocina diminuisce più lentamente raggiungendo livelli normali in diverse ore. Oltre a raggiungere l'orgasmo, l'altro meccanismo per elevare il livello di ossitocina è toccarsi e accarezzarsi, non necessariamente in un modo sessuale; anche il semplice tenersi per mano aumenterà i livelli di ossitocina.
Anche quando il livello di ossitocina è ridotto a livelli normali, anche se la sensazione di legame potente va persa, la memoria di quella sensazione rimane. E' la memoria che fornisce le basi per relazioni a lungo termine per sopravvivere montagne russe dopamina / prolattina.

Dopamine - the neurotransmitter that causes the feeling of pleasure we receive from engaging in certain activities. Sexual arousal, the eating of calorie rich foods, and for some, certain other behaviors like gambling or shopping, and the ingestion of certain drugs like cocaine, amphetamines and heroin all raise the level of dopamine in our reward center.
This rising level is experienced as pleasure and the higher the level, the more intense the pleasure provided there are sufficient receptors to accommodate the rising level. The intense pleasure of orgasm that we experience results from the sudden flood of dopamine that is released in the reward center of our brain.
Prolactin - the neurotransmitter of satiation; it applies the brakes, so to speak, on the level and duration of dopamine and oxytocin ( it affects oxytocin indirectly by its effect on dopamine). Prolactin levels generally remain stable in the reward center of the brain except during orgasm when they are substantially increased to deal with (i.e counteract or reduce the level of) the sudden flood of dopamine and oxytocin. The elevated levels of prolactin after orgasm persist for a minimum of one week and as long as two weeks
Oxytocin - often called the “cuddle hormone,” when the level is elevated, it produces the pleasurable feeling of bonding or “connectedness,” as well as feelings of closeness, devotion and protection. It is the primary factor in establishing the basis for pair bonding. A burst of oxytocin is produced during orgasm and is responsible for the post orgasm afterglow of love and connectedness we feel.
After orgasm, in men, the level or oxytocin quickly drops - in less than an hour it is well below the level it was at before sexual arousal began. In women, the post orgasmic level of oxytocin decreases more slowly reaching normal levels in several hours and remaining there. In addition to orgasm, the other mechanism for raising the level of oxytocin is touching and caressing, not necessarily in a sexual manner; even the simple act of holding hands will raise oxytocin levels.
Even when the level of oxytocin is reduced to normal levels, although the powerful bonding feeling is lost, the memory of that feeling remains. It is that memory that provides the basis for long term relationships to survive the dopamine/prolactin roller coaster.
