Friends with benefits sex, video 5 minutes 11 seconds.

Sometimes when I see some boys in Taiwan writing about hookups, they say "each takes what they need"⋯
I often wonder, what does his "each takes what they need" mean?
Some also write "paid hookup".
I don't know what other girls think, but I've been trying to figure out my own "true thoughts".
When I see boys writing like this, why do I sometimes feel very disgusted?
Why exactly?
If I were a man wanting to hookup, how should I write to attract girls' attention or favor without making girls feel disgusted...?
