Hey Sirsarcastic,
To better share our own relevant experiences, can you please elaborate more on how long have you had your implant? What brand and model is it? Did you suffer any penile condition, aside from ED, before getting the implant, and for how long? Can you be more specific about the type and place you are experiencing the pain, and also what is your definition of lot of sex/masturbation?
All those variables can help us to understand better your situation, and get better answers from the forum members. However, remember that we can share our experiences, but the best source of information should be from your surgeon.
Cheers!

PS: While I am asking you all the questions, I am realizing that having a standard forum signature with basic background information will help to avoid repeating that has been shared before. I need to create mine, so I am not preaching you at all. I am self criticizing myself
