How do i know when my voice will break ?

There's no way of knowing, it's like the rest of puberty, you never know what's happening next.

Don't worry about looking young, you'll be grateful for it when you are older.

I'd say pretty soon dude, just give it a couple of months. Mine started cracking at about 15 1/2. I used to get joked on all the time for having a high pitched voice, but my voice is pretty deep now.

it will crack sooner than you think. Most likely at the worst time too. I lucked out because to me it happened during summer vacation. Others where not so lucky. Anyways, what does penis size have to do with anything. Just go to school, study hard and play with your friends. Have fun and meet people. All this girl stuff dating and what not will happen all in due time.

someone you havent seen in a long time will tell you ur voice has changed.

or you start sometimes when you talk loudly or laugh or scream whatever. well your voice will go high piched for a sec yea

dw your voice will break soon enough, and let me tell you,, the squeakier your vooice is before it breaks, the deeper it will be when it breaks. alos, there will be a few months transition period where it will be really messed up LOL

dude im the exact same way here and it sucks rite?

im already 15 and nothing has happened

there's no way to know for sure, it will just happen, your voice will start cracking while you're talking.

You'll know when it starts to yo-yo.

you don't
