Should I go for this girl:

[Lily Crowley]

This just makes me sad. Why would it matter how many people she has had sex with before you? Why would it matter that some of her encounters were threesomes?
Your usage of the word "cum-bucket" is also very degrading. (I know you said you didn't want to use it, but cleraly that is what you are thinking). She is allowed to like casual sex with whomever she pleases. If she has done this in a safe environment and protected herself, what is the problem?
Even if someone has had many encounters and used sex as a recreational activity that doesn't automatically mean they're easy and will immediately cheat in a relationsip.
If she is interested in you in more than a friendly/casual way and she is a decent human being otherwise, she'll be faithful.

This thread just reeks of "Women are sluts when they have had many partners and are not wife material, whereas men are awesome if they've fucked many girls!"

Men actually get slut-shamed just like women, in addition to being shamed if they choose not to pursue sexual activity.

No it doesn't. People just stated what they would do if it was their case and the rest of them (including myself) just pointed out that OP needs to talk to girl and find out if he wants to be in a relationship with her or not. And yes as hard as it seems being very sexual active as in a lot of casual intercourse (goes for males also) can affect the persons relationship trust, as in she could cheat on him in majority of cases. But we don't know that, do we, since only OP knows the girl. Hence why none can give him a proper answer, only he can.

What's the problem? I'm betting you wouldn't pass up a chance for a threesome yourself. If you like her, go for it.

[Gnasnimadan]

Ask her if she would feel like a threesome with another girl

[Kakazam]

That's not necessarily the case, but if it is, so what? Casual sex isn't the devil.

Indeed, however I personally don't like the thought of going out with someone who was banged by two guys at once, never mind on multiple occasions. In my head all I can hear is an alarm bell ringing 'slut slut slut'. Also to sound completely hypocritical, I would most defiantly have a threesome with another guy and a girl, I just wouldn't want to have a relationship with the girl.

It all comes down to the lock and key metaphor in the end.

Also before people start arguing it's double standard for men to do one thing and women another, girls have it easy. Don't even try get liberal/feminist on the topic because it's a blatant fact, just like most species of animal.

This is not a question anyone can answer for you.

Why yes it is. The answer is say goodbye. Leopards do not change their spots. I see bad things in your future if you keep her.

[Mionelol]

I don't understand how does this matters in the slightest.

i have yet to actually see the former ever happen.

Well people change just because she used to be promiscuous earlier in her life doesn't mean she still is.

In my experience people don't change, but, their opportunities do.
