When she and Rachel then lost the final question, they were forced to swap apartments with Chandler and Joey. However, they won their apartment back several months later by agreeing to kiss for one minute. It could also stem from her childhood and teenage insecurities, particularly as her best friend, Rachel, was a popular school diva with several boyfriends, whereas Monica was obese and relatively unliked. Monica is notoriously bossy, and she is often referred to as such by her friends.
Her controlling behavior is best seen in her relationship with Chandler, where she frequently wins the upper hand in their disputes.
Now, we are also swingers. We do have sex with people that we are not in love with. We do, however, care about people and we prefer to get to know people first before sex. We have been known to get it on on the first meeting if the chemestry is right.
Swingers are such a diverse group of people and there is room for whatever ones heart desires.
