Is it normal that i don't wanna ask out my crush?

Sometimes it's fun to just have a crush and that's all. I've had plenty of crushes that I would never really consider going further with even if my affection was returned. I think it's normal.

How will you feel when she ends up in a relationship with someone else? Would you regret not taking a risk then? It's normal to pass up those opportunities, lots of people do. They just learn to accept their regrets.

She gives the best head in town so go for it.

I've had friendships with women in the past that I knew would turn to shit if I had started a relationship. But the thing is some of those friendships turned to shit anyway. Might as well get laid if it's gonna turn to shit regardless.

Depends how big the chances are that she likes you back.

You don't have to tell her. It's up to you, stuff like this can change a friendship.

So if you feel like it's information she should have, tell her in the future when the time is right.

Not to be at all mean, but I don't believe "I don't want sex, kisses, intimacy" for a second.
If you are a healthy, well adjusted male,of course you want sex, kisses, intimacy with somebody you have a crush on. That's exactly what a crush is.
I think you should plan a campaign for getting her as your girlfriend. Bring her flowers and see how she reacts. If her eyes light up and you get a big smile, you're half way there. It's the little things, like saying how nice she looks, things that will and allow you to gauge her response. If positive, pursue her, ask her out and do fun things together. Things out of the ordinary, like the zoo, or a hike, or even skating or bowling. There's nothing better than having your best friend also be your lover.

Sounds like you are just shy about it.
