Amarte Así (2005)

As a teenager in Mexico, Nacho discovered that he could seduce girls by giving them gold rings. With his buddy Lucho, Nacho fornicated with many, many girls, then never went out with them again. Sometimes Lucho "helped" Nacho by putting a date-rape drug in the girl's drink, though Nacho was not aware of this. Being from a rich family, when Nacho finished high school, he went to Los Angeles to study medicine, not knowing that on his last night in Mexico he had impregnated Margarita. Lucho had actually drugged both Nacho and Margarita, leading to lack of inhibition and fornication.
