I want to go give a bj to someone but i'm scared to ask

Wait until you are in a loving relationship, because it will be more enjoyable, and more special.

U can give him signals by looking at his crotch when he is looking at you, and hope he notices and if he will go that way, I don’t think I would ask him, if it dosent work out and u wanna give head, go to your nearest adult video store go in the back video booths, there’s always guys looking to get sucked off

Try hanging out with him after school and see how it goes, flirt a little bit and take your shot, ask him. If you dont take risks, you wont move forward

Any guy who will let you suck him, as a complete stranger, has NO respect, for you, or women, in general. But, if that doesn't matter, to you, at least find a guy who isn't a "player" and will give you a SERIOUS disease.

Just ask him "I'll suck you if you like".
Most guys will beg for it.

You say “some guy at school”. Does that mean “any guy” or a “particular guy”? If it is a particular guy and you can talk with him, just tell him you would like to suck his hose. He may be happy to oblige your craving but then, on the other hand, he may find it amusing and share your offer with all his friends and relatives. If it is any guy’s hose you want to suck just select the one guy you feel is most approachable and let him know you would like to suck his hose. He may be happy to oblige your craving but then, on the other hand, he may find it amusing and share your offer with all his friends and relatives which would be a good way for you to advertise your interest in sucking hose.

Are you male or female?

Pick a guy, get to know him a bit and tell him what you want to do.
Most guys would agree in a heartbeat.

I remember my first blowjob in school in the gym teacher's room.
Man, that girl was amazing. She was very skinny. I was absolutely mesmerized by her skinny, sexy body.
It was an amazing blowjob and some of the best sex I've had in my life. I was so hard it hurt.

Just grab it in his pants and play with it in private.

Haha naw, Idk. Maybe...uhh..see if he likes you. If he likes you its usually easy to turn most guys on. Ask him how your butt looks in your new jeans or something. Let him catch you checking out his bulge. Idk im not s girl idk how yall do it

Just ask him in private. I cannot imagine any kid in school would turn it down. I would have never turned that down, well maybe a couple of exceptions, maybe.

See if they want to have a drink or smoke some weed wid ya on friday night.
