Answers:
Usually after sexual intercourse, there is a surge of oxytocin, dopamine, epineprhine, noepenephrine, and other natural neurotransmitters. The drug that primarily give the pleasure during climax is oxytocin, the sexual drug. Oxytocin is also responsible for the production of lactic acid (for breast feeding), and is present during childbirth. This drug is responsible for the powerful relaxed feelings. The lack of concentration would be because of the giant amounts of dopamine and lower amounts of seratonin. Hope I helped!
