Anthropologist Helen Fisher answered some questions on the subject.

Love at first sight does exist and sex "casual" is not so much. The questions that we often do when we are sexually attracted, or lovers, are answered by the American anthropologist Helen Fisher, who will be visiting Puerto Rico under the Congress on sexuality that will be held on October 4 in Hotel San Juan.

Why the love produces anger, jealousy, sadness and joy?


We are creatures who make a couple of links to raise children. We are in the 3% of mammals that do. For this brain systems for romantic love and the link is so powerful, primary and primary.



Are love and sexual relationships?

Yes, any sexual touch boosts dopamine to the brain, the main chemical reward system that is directly associated with intense feelings of romantic love. Moreover, with orgasm, you receive a flood of oxytocin and vasopressin, chemicals associated with the attachment. Sex also raises testosterone, the main chemical sexual appetite. Therefore, having sex with someone you can shoot any of these three brain systems: more sex, feelings of romantic love and / or feelings of attachment. In short, casual sex is never casual.



Does love at first sight?


It comes from nature. All animals are attracted to some animals and not others, and this attraction can occur instantaneously. It occurs in about 10% of people that the system of the brain dopamine reward can soar instantly.
