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.
Vinegar - Just sprinkle liberally on rash or blisters for instant relief from itch. caused by poison ivy. Although the smell may not be to everybody's liking, vinegar seems to help draw out the poison from poison ivy while it also helps healing. White distilled vinegar or apple cider vinegar seem to work best.
