I would like to enlarge my nipples safely. What is the best way?

If your nipples are inverted, there is a simple operation to bring them out. It can be done under local anesthesia in the office. If they are simply too small then the simplest solution is an injection of filler, A photograph of your nipples would be helpful here.

Enlarging your nipples is more difficult that decreasing them. Suction cups like you are doing should be effective but you need to do this 24/7 and for a long period of time!
