Crazy isssues of Love..

Hello again!
Well to tell you the truth, I am not an expert on love issues. In fact I have some problems of my own for example, I do not have a boyfriend!!(I mean it so embarrassing that I can hardly mention it). I mean everyone has a boyfriend 'cept me!!...But to tell you the truth I don't find any guyz upto the mark I want. One of my friends says that i have high expectations but i wonder how. I mean everyone wants their bf/gf to be perfect as in good looking, smart, funny, understanding, loving, caring, brave etc...
I really don't get the fact that how to deal with hormonal changes like crushes, infatuations and frissons. Many times due to frissons you act really stupid and dumb like when he/she(your crush) asks you about your day, you just stand there, staring at him/her like an utter moron and say something that only an alien can understand! You make a complete fool out of yourself! There is gotta be a way of avoiding such social faux pas.
I am quite sure there are many unknown people like me who have such horrible issues!! Whoever reads this, please do help me in finding solution to this problem and save others from making a fool out of themselves.
