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.
Poison ivy rash is caused by an allergic reaction to an oily resin called urushiol (u-ROO-she-ol). This oil is in the leaves, stems and roots of poison ivy, poison oak and poison sumac. Wash your skin right away if you come into contact with this oil, unless you know you're not sensitive to it.
