Do you think this vibrator here is safe to be used on the penis?

Is it dangerous? Doubtful.

Before I got my first Aneros three months ago, I was exploring other alternatives to Plain Jane masturbation. This lead me to purchase a Hitachi Magic Wand along with a dimmer switch to give more than two options for intensity.

What I found was an initial difficulty to experience anything. In the beginning, I needed massive amounts of vibration to have any enjoyable feelings but this came at a price. Numbness would quickly set in and ruin any progress. So, I changed tactics and used the dimmer switch to go a lot slower. Eventually I found that less equaled more and found a sweet spot that would generate an ejaculate orgasm. But I also found that area, with repeated use, became a bit discolored. Most likely it was a slight bruising from small capillaries rupturing. There was no pain or soreness involved which led me to continual use; but, I ceased using the wand around April after I ordered my first Aneros.

I have my doubts there is any real threat of damage from vibration. Especially since the Hitachi is bound to be far more powerful than the item you posted about, and I fully intend on trying the wand again in conjunction with my Helix Syn very soon. Might even use it directly on my MGX since it's more rigid.

All in all, I found the vibration orgasms quite interesting. A good departure from standard masturbation. It was very cool to place the wand's head on that sweet spot and let the vibrations do all the work. After awhile, I even enjoyed seeing how low I could set the vibrations to achieve orgasm. Sometimes the sessions bordered on torturous but those sessions usually generated some excellent outcomes.

Overall, our bodies are pretty resilient. As with any new venture, take it easy, and be mindful of any new changes, good or bad.

Hi, this toy which I have only has 2 speeds so you cannot adjust very much. This sucks.
I'd like to try a Hitachi but they are so expensive.
But I'm still not sure if it's safe to hold something against the penis which vibrates very strongly I mean this isn't natural.

The hitachi also has only two speeds, unless you add an external controller. You'll definitely want speed control. Other wands in the style of the hitachi have built-in variable speed, e.g. http://www.amazon.com/dp/B004UM8MWW

Before I got into aneros product, there wasn't much I liked better than rubbing my wand against my cock, or squishing into a rubber sleeve attachment.

For what you get, the typical $60 US price is very reasonable. It can actually save you money since you won't want to buy another cheap vibe. Or batteries.

Just don't be a dumbass and you'll be safe. When you start to feel any discomfort, turn it off. Not complicated.
