There's no bigger turnoff than asking someone out only to discover they're completely fake, or they are too insecure to be his or her self. He/She asked you out because you caught his/her attention with your personality. You might be really nervous about cracking jokes and being as comfortable as you are with your buddies, but the key is to relax.

There's no need to get so nervous, the more you can relax, the more your date will see the true you. If it helps, your date is probably just as jittery as you are. Just chat it up and try to enjoy yourself.
