Dear Dr. Yvonne, Does a woman run the risk of falling in love with me when we're just having casual sex? -Marty

Dear Marty, While not a general rule, research shows that sex does promote bonding. Although people don't plan on or want to fall in love from casual sex, they may since such intimacy triggers hormones that have a romantic effect. Dopamine spikes with orgasm, changing the threshold of your ability to falling in love. Orgasm also floods your brain with oxytocin and vasopressin, chemicals associated with attachment. Furthermore, if a man is depositing his seminal fluid in a female partner, he's giving her a dose of the chemicals needed for sex drive, attachment and romantic love. This increases her chance of falling head over heels.
