"This is a video of my first successful testicle injection. I injected about 8ml of saline. It was definitely a lot more exciting than scrotal infusions :).

In a previous attempt I managed to inject only about 1ml and stopped there. The needle does not hurt much but pushing the saline in is quite painful. Once you stop the pain quickly disappears, though.

The end result was a slightly bigger and rock hard nut for about 30 minutes!"
