the correlation makes sense though . women that lots of casual sex with lots of different people less likely to enjoy fucking the same person for 20 years . i mean that makes so much sense that i dont even need a study to tell me that . a girl generally doesn ' t see a player as husband material either , and why would she ? he spent the last 5 years of his life smashing every pussy in sight and having fun , could that guy REALLY be monogamous for the next 30 years in a marriage ? probably not . i might get downvoted to fuck but this is just my opinion , and my opinion is that humans can ' t have it both ways , we can ' t be BOTH into casual sex all the time , and great in monogamy . people are cut out for ONE of the OTHER . some people just can ' t do casual sex alot , they can ' t have sex without weird feelings and stuff getting involved , so they can ' t enjoy it , they need monogamy and relationship sex . some people just love casual sex and can totally fuck anyone , and have a great time doing it , with 0 weird feelings involved , these people are not good in relationships . hence , i probably wouldn ' t take a girl seriously as relationship material if i knew she had a huge history of sex for fun with guys she didn ' t know well . i mean that is just my intuitive logic that makes sense , and studies actually support it . i dont think sluts are bad people , but i just doubt they can be good at monogamy . I cant fuck random girls without feeling weird and getting feelings for them and feeling empty after wards , casual sex isn ' t for me . i also just can ' t relate to a girl who can have casual sex .
