My struggle with them

You know, boys. Men if you will. Ok so not just any guy, I'm above average at interacting/not looking like a bone head with guys I look down on. It's the ones with the features that can make me sweat and lose my cool that I have trouble with. Every. single.time. I can go about ruining my encounters in different ways, but the results are usually very consistent.

Example 1: I'm walking down the hall with one of my friends looking exceedingly great at being a human. Talking, laughing, walking,you know looking like I've got things going for me. I make some comment to the friend and this hot guy intervenes looking all friendly and well ,hot.

Here's my thought process: here is some guy that's actually engaged you for an opening in a conversation with a great physique. You should give him some idiot one word answer so there could be no possibility for him to reply.

I don't need to go on do I?

Example 2: Never do I sit by any of the hot guys(only applicable this semester) in my classes. My brain thinks the exact opposite of any normal person. I'll just sit the furthest away from them, act repulsed by their presence in the class,and never so much as let a syllable slip from my lips to them. It makes sense at the time.

Example 3 (probably my favorite): Silence. Yes, that's right. Now usually in a social setting, this happens when the male in question has in my mind descended from a cloud. I should just be humbled that he was willing to be in the same party, state, country, solar system. This is my highest state of nervousness, brain function and body movements cease to exist. Thus, putting on the invisibility cloak over myself to the particular male goddess and even close acquaintances.

Don't think I want a boyfriend,but I do eventually need to improve some of my methods to eventually convince someone to be with me. Any tips would be appreciated.
