What's the difference between a sexy girl and a beautiful girl?
This seems to be like asking "what's the difference between a delicious meal and a nutritious meal?"
They aren't mutually exclusive nor inherently linked. Someone can be beautiful and sexy, someone can be beautiful but not that sexy, someone can be sexy but not that beautiful.
Sexy and beautiful are two separate words for two separate things.
If you need to know a "difference," there are things called "dictionaries," not to mention a "thesaurus."
The sexy girl immediately turns you on whereas a beautiful girl looks beautiful but doesn't turn you on.
Huh?
So if I see a beautiful girl and get turned on, then it means she's not really beautiful?
Generally men want instant gratification
Generally, people want instant gratification. It's not gender specific.
they go for the sexy girl rather than the beautiful girl.
So are you saying if a girl is sexy, then it inherently means that she's perceived as "easy" to get, fulfilling that instant gratification?
So a woman that is perceived as not leading to immediate gratification could never be considered "sexy?"
And of course, because she's considered "sexy" then she's not beautiful?
The secret of course is that the beautiful girl should also look extremely sexy!
Based on your earlier statement (" a beautiful girl looks beautiful but doesn't turn you on") this is just going to lead to some circuitous mental problems.
It's just going to lead to confusion, miscommunication, that's ultimately going to drive people away, as it's going to lead away from thoughts of instant gratification towards trying to resolve if they're beautiful or sexy because a beautiful woman is turning them on which means they aren't beautiful.
Good luck with that.
