Lately I found out I could stop an ejaculation even if it has already started - while the semen is attempting to get out, I pull it back as if I'm trying to stop my self from peeing. That causes only a tiny leakage of semen, and the rest seems to get back into my body.
After that happens, I feel a little discomfort in that general area but the "pleasure mechanism" just resets and I can masturbate again and ejaculate later.
I've done this twice, once by accident and once on purpose, and both back then and now I can't imagine this technique not being unhealthy.
As such, I have 2 questions:
1. Is this normal? Can most men do it?
2. Is it unhealthy?
Thanks!
