Boys start to ejaculate normally when they start going through puberty and obviously start masturbating. But some guys cant ejaculate until my later during puberty. The age that puberty normally starts is around 11 - 13. I hope I have helped.
To eradicate poison oak and poison ivy chemically, use an herbicide that contains glyphosate, triclopyr, or a 3-way herbicide that contains 2,4-D amine, dicamba and mecoprop. See Table 1 for products containing these active ingredients. These herbicides can kill desirable plants, so be careful. If the poison ivy or poison oak is growing among plants you want to save, you can cut back the poison ivy or poison oak and spray or paint the herbicide only on the freshly cut stems or stump.
If you think you have touched poison ivy, rinse your skin with cool water right away. Then, wash it with soap and water. Rinse your skin well. Do not use hot water because it may cause the oil to spread on your skin. You may also put rubbing alcohol or a solution of 1/2 alcohol and 1/2 water on your skin.
