Kiss? When you feel like it. When it comes to french kisses and the like, most young teens find it too awkward. It graduately evolve with experience and trust.
Make out? What is the definition of making out again?
Masturbate? As the lust comes naturally, it will come when it comes. Consciously pleasuring yourself is okay when the need begin, I guess.
Have a boy/girlfriend? When you are able to handle this. There is a lot of responsibility involved in a relationship, and there is also a lot of conflicts. To some point I even find it too young to have a boy/girlfriend when you are sixteen, simply because there is so much involvement in this.
Have sex? When you are able to handle the responsibility. Really. If you are able to handle it in your mid teens, then fine... And the responsibility is not "Oh noes, pregnant!" but being able to care about your partner, to not just be a fool about it. To be able to buy condoms by yourself, and have enough knowledge about protection and the mechanics of this kind of intimacy. Know the facts from the myths.
Hmm, well, I actually dislike people doing so in public... It annoy me... But I guess my answer is, again, when you are okay with it. When you are not feeling embarrassed or awkward. And when you are able to get someone to make out with, as well.
