That line must net some psycos!
Psychos*
Honestly I just say:
I'm not looking to date you, and I believe in being honest, so please respect my honesty when I say this...
You are breathtaking and the way you carry yourself is very sexy. You have this aura about you. I just really want to fuck you. Until you can't walk. I know it seems vulgar and way to up front but I don't believe in having to lie to you or trick you into sleeping with me. You deserve the respect to know my intentions. I know you are clearly not a girl who sleeps around, but I just had to put how I felt out there.
You'd be surprised how many respond to that. Just need the balls to say it. Whores are whores. They just want to be respected.
