Isen't te quiero i want you, since quiero or querer is to want, instead of i love you'
"Quiero te" isn't proper Spanish. "Te quiero a ti" can be said for emphasis ("I don't love any of those other girls, it's you I love.").
I know from experience that "te quiero" is used for a wide range of emotions, everything from a passionate lover to a grandmother to a dog.
If you want to say "I want you" in the sexual sense, it would be te deseo.
Also, if you want to say "I love it," it would be me encanta.
it depends if i say yo te quiero i am saying i love you but quiero te means i want you
So then how would you say, "I want you to scratch my back'"
Its "I love you", in a more informal way (as in something you might say to your girlfriend at the end of a phone conversation).
At the practice "te quiero" and "te amo" represent something like scale. So you may use "te quiero" with your pharents, sister or friend, and you say "te amo" to your girlfriend or boyfriend.
thanx for clarifying that
It's also I love you, however I prefer te amo
