When a woman shit tests, she is usually testing for value, but often they will test for comfort instead. With a value test, you pass the test by demonstrating higher value e.g. by agreeing and amplifying. Comfort tests usually come when you make yourself seem unattainable or like a player, or when a woman is looking for a relationship. You pass a comfort test by assuaging her concerns (without supplicating).
This particular question strikes me as a comfort test rather than a value test. If it's coming this early then you were probably overqualifying yourself (i.e. using too much game) and either coming off as a try-hard or a player, rather than the alpha that she wants to tame.
To answer your question, I would say "I'm just looking for someone I click with". This response also works if she asks if you're a player. A DHV (like "I'm currently building a harem and there's an opening for Bottom Bitch") might work at first but she'll ask again further down the line, and she might eject right away if she's insecure. Otherwise, if she's a slut, she'll just put you in her "one-night stand" mental box (which is fine if that's what you want, but that's
if she's a slut). So you comfort her (but, again, without supplicating).

1)oh no no Im a good guy I dont do such things (fail)
That's only a fail if you say it in a supplicating way. Said with a smirk and a sarcastic tone, it would be a pass.
all the girls want to take advantage of me
(or "I'm sick of girls just using me for sex")
This is a 10/10 five-star grade A+ if you say it right after sex. It instantly marks you as a high-value alpha male looking for a relationship. Look her in the eyes when you say it and there's about a 60% chance she'll fall in love with you right then and there. Okay, I'm exaggerating, but it's a good line. Just don't ruin it by saying it with a whiny voice.
