I use Peni Master pro. I have had the opposite experience. My glans has increased in size, slightly but bigger then before. I would play with the different size adjustments it may be that you need have a smaller opening to create more suction. I had to use the middle size adjustment and that increased my glans upon
Removal of the unit.
Regarding a supplant for erections. I started using Alpha Viral made by HFL back in August and I had amazing results. It worked right from 1st week and by 1 1/2 months it took me to a whole new level and at the 3 month mark it got even better. I tried
Cialis and Viagra and it worked at first but eventually stoped working. If you like Alpha Viral you may want to also order Blood Optimizer which is made by the same company. They work well together but i just used Alpha Viral for the 1st 3 months and had great results.I hope this helps.
