> I want to meet a nice guy
Good start. Guys want to meet you as well.
Here's another thing you have in common with them off the starting line: They know as little about you as a person, as you do about any one of them. Before they get to know you by spending time with you, asking questions and seeing and sensing what you enjoy, they won't know what the "right thing" is for you in many circumstances either.
It is fun taking small steps, and finding out about each other (and can be very funny after the event looking back together on things you tried with best intentions, that didn't work out).
I suggest starting off with someone with a similar level of experience of relationships (ie don't hit on someone you know to have had many more relationships than you).
>when they want to hang out and get to know each other more I get so scared and I don't want to even talk to them anymore
The key is to keep the steps and the risks small and controlled until your confidence builds, you have good reason to think he is really OK. When you start to know a guy and trust him, tell him more and do more with him.
> I'm so scared that I'm going to do something wrong
So's he if he hasn't had dozens of partners before you. Give each other a break. If he doesn't always get everything right for you and with you, tell him calmly without making a federal production or making him feel a total a$$. With a bit of give and take you can have fun teaching each other a lot.
> I'm that type of girl if I do and he points it out I just don't wanna talk to guys for a while
Because of embarassment or because you can't tollerate getting feedback you've done something wrong from anyone?
If it is the former, don't fret about it - you won't just luck into getting it all right first time. Great advice from KennyK about learning to laugh at yourself.
If it is the second, that's something you need to work on for all your relationships, not just ones with guys, but work, and life in general as well.
