I have been trying this since i started ejaculating, cause very often i did it not in my bathroom, so not every time i had to clean it up. One day i acquired the capacity not to ejaculate when i have an orgasm. Sometimes the orgasm is much more violent (bigger sensations). It's been now about 12 - 14 years i do that. Now, I'm wondering if it's safe doing that. I have tryed to find informations on the net but no success. I would like to know if some of you can do that, why do you do that, do you think it's better etc.
