Yes, they do.
If by work, you mean help prevent various diseases, decrease the risk of pregnancy, give the other sex partner something to do with her hands in addition to the other parts of her body, reinforce the male's feeling of responsibility and concern about disease and an unwanted pregnancy in his sex partner, reduce stress and set sex up for fun and games, and mostly fun, yes, they work. At least, most of the time.
Otherwise, they are a waste of time, and are sort of like wearng socks when washing your feet.
Then, on the other hand, having sex without a condom is not altogether like washing your feet with socks off.
Nobody has ever gotten anybody pregnant at 13 and really screwed up at least three lives by washing their feet without socks.
You can, if you have the right sperm count, the right circumstances, and the right time of the moon, get both someone else pregnant, and set it up to die from various diseases, or just suffer a lot in your youth*, if you don't use a condom.
All at the same time, just not knocking somebody up does not mean that YOU do not get the clap, AIDS invitations, and history's finest veneral diseases. Lots of good books on the facial malformations and rotting away of the brain from good ole' sexually transmitted diseases....
Remember, search engines are your friends.
And condoms are cheap.
* This seems to work at other ages, also.

No! You should find someone your own age! Or wait for him or her till you guys are older...
A 13-year-old boy absolutely CAN impregnate a girl. Use condoms!
12 year old guys like girls who are funny, pretty, and realize that guys have feelings too.
Be serious, condoms don't always work, knowing you've already found out by now, but condoms only work 99.6% of the time, and even then putting it on slighty wrong can causer it to split :p

I'd say go for it, as long as you use condoms.
A fourteen year old shouldn't even see a guys balls. So, the answer is no
Yes.
