I have been using this technique for over 15 years. I worry that it could somehow affect my prostate or something, but honestly if it goes into the bladder it's no big deal. I do this once a day on average. If i do it more than once a day there can be a dull pain.
The old lovelines radio show with Dr. Drew addressed it once and said it was safe.
On a personal note it basically makes me able to masturbate anywhere, have sex anywhere without cleanup, and also girls love it when they blow me and i hold it in, i get the orgasm, and they don't have the taste.
In short, it's probably safe.
