Question: Girls, is it true....

I usually know within the first couple minutes of meeting a guy if I would ever want to sleep with him, if it's a no, that I usually rule him out altogether. If I don't eliminate the guy, then it takes me longer to fully decide whether I would ever sleep with him, because It's hard to decide on a blink whether you would have sex with someone without knowing their personality.

No. I know within 5 seconds of looking at a guy if I would never ever sleep with him, but other than that only time will tell. Sex is not that easy for me to just look at a random guy and be like "Yep, I'd do him"

within 1 minute I know if I definitely wouldn't ever sleep with a guy; they are immediately eliminated.
but as for the guys who aren't immediately eliminated, it takes a bit longer than 5 minutes to decide.

Possibly but it would require a big deal breaker: like a smoker hitting on an avid non-smoker or something like that. I would say that a girl most likely will know whether or not she wants to invest the time to get to know you better in those first few minutes. It's important to be yourself and honesty and openness will get you a long way. :)

This is actually partially true from what I've heard.

You could find out by talking to a bunch of girls for five minutes and then asking them if they would sleep with you. If they all say no, you know this is true.
