How can you tell if someone is good in bed before sleeping with them?

What kind of things would you keep an eye out, or pay attention to, to make a good assumption as to whether someone was good in bed or not?

By "good in bed" I guess I just mean, someone who knows what they are doing, someone who is enthusiastic and fun in bed, someone who pays attention to the "little things" etc etc

 

1) The way they flirt with you.
2) Body language.
3) If they go into elaborate detail of explaining what they would do to you in highly erotic and sexual situations.

...Those are usually good indications.

 

In my expierence people who talk about sex all the time really don't know what to do when it comes down to it.

 

Me too.

 

Hey yea sarahrei has it in one all talk no action ,

 

i find that if they can dance there usually good in bed. ya know the whole with the beat is like keeping in rythym.

 

I find that it's pretty random sometimes I would take a girl home and be thinking (oh god this prude bitch) and I couldn't handle her wild pussy and crazy sexual tactics and other times I'm really looking forward to it and it sucks ass. I kinda think it's just a natural thing where some people click and others don't, because when I fuck I go it to crazy sex mode where I turn into a crazed fucking animal and don't really think I just act so if a good percentage of peeps are like me there's really no way to tell IMO

 

I used to observe them around dogs and cats, someone caring enough to take the time to pet or rub a dog or cat in such a way that gratified the animal ( not in a sexual manner, though with pets it's difficult to be sure) would most likely express that same caring, sensitive, nature with a human partner such success with animals requires acute observation of what the animal accepts and rejects on a non-verbal level so think what they could do with some verbal requests, in addition their willingness to do this with animals indicates patience and concern for even lower creatures which usually translates well with humans
