I want to know the answer to the following question:
What activity often results in a boy's first ejaculation?
All the background I'm provided with is that "The first ejaculation of seminal fluid generally occurs about one year after the beginning of accelerated penis growth, although this is often determined culturally rather than biologically, since for many boys first ejaculation occurs as a result of masturbation.". Is that enough to answer the question?
Answer: yes
