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.
Wash anything that comes in contact with poison ivy to remove the oil. As you know, the rash is very itchy. It usually lasts about three weeks. For mild cases, you can use cool compresses, over-the-counter oral antihistamines, and hydrocortisone cream applied to the skin. For more severe cases, see your doctor.
