I've actually never been on a date before. Every single relationship I've been in has grown from friendship with people I've already known for some time. This is the first instance where I just simply asked a woman I did not know on a date and I'm really nervous about the whole deal. Hell I was actually nervous just to ask her in the first place which was unusual because I've never had any problem talking to women before.
I have no idea how to act or what to do or what to wear. What should I do or say? Any help or advice you can give would be really great. Thank you.

Note: I'm in this for a relationship and not just getting laid.
