a few simple steps

if a girl and a guy are sexually attracted to each other

if they talk to each other 

and they like to talk with each other 

then they can hang out with each other 

and if they like to hang out with each other 

then they can have sex with each other

and if they like to have sex with each other 

 

then they can have more sex with each other 

and they can hang out more with each other 

and they can talk more with each other 

if they like each other, then they don't need anything more than each other 

and possibly some more girls to have more fun and more drama
