So there's this boy..

Try to flirt a bit, do it real sly like so he don't know. If he responds, push it a bit further each time, remember: BABY STEPS. When he flirts back quite a bit, then ask him, not straight out "Do you ant to go on date with me?" That's a big no-no. Ask him to go do something with you when there are friends around, like going ice skating or something with a group of others. Then get him a little bit alone and hang out. Also, if a rumor that you and him are going out (if your'e in school or something) ask him how he feels about it. Hope this helps

It's hard to say, it really could go either way if you tell him so if that's what you want to do, ask yourself 1st if you're willing to chance the possibility of changing the dynamic of your friendship. You could try flirting with him and see if he's receptive to that before actually telling him how you feel.

Yup and maybe hint at it and see if he seems to like you. Nothing wrong with that at all

Don't have sex till later a lot later and pretection

COMPLETELY NORMAL, Go to a queit place with him aeay from home, say your cold and if he hugs you, he likes you, if he puts a sweater on you, he likes you. If he tells you to suck it up, he doesn like you. :)
