it depends on how much developed you are. 16 is kind of late to be "just starting" but it is possible. have you had a wet dream yet? if not,your body might not be ready for this. you can email me if you want to discuss youe particular situation but here is some basic advice. there is a muscle between yolur legs, if you peniis is like half hard you can make it stiffer by tensing this muscle. you need to tense this muscle when you stroke. tense and stroke for 10 to 20 seconds, then relax a few sec, then repreat. speed about 1 to 2 strokes per second. then if you start to feel a tingling, or like you need to pee, then don't stop, start stroking as fast as you can for as long as you can, and that might be enough to push you over the edge to climax. hope this helps. I am a parent.

Biofuels <--- Made from stuff like animal crap and leaves. Produces less greenhouse gases than fossil fuels but also produces less energy. Renewable because there is a ready supply of them, particularly the former.
Carbonaceous (or fossil) fuels <--- Made from the remains of prehistoric animals (oil and natural gas) and vegetation (coal). Produce a lot of CO2 and the like but are the main source of energy in the world today. Non-renewable because they take millions of years to form.
