It sounds like you’re navigating a challenging recovery process after your surgery, and it's great to hear that your desire for intimacy is returning. Many men report varying experiences with vacuum pumps and medications like Viagra, and it’s not uncommon for it to take time to see significant improvement.

Regarding your question, some users have indeed experienced a delayed response where, after several months of using a pump or other treatments, they suddenly notice a positive change. Factors like increased blood flow, psychological readiness, and stimulation can all play a role in this process.
Since you mentioned that you haven't yet tried stimulation from your partner, that could be a helpful next step. Physical intimacy can sometimes enhance arousal and improve response. Additionally, the injections your doctor is arranging may also provide a more immediate effect.
Keep communicating openly with your healthcare provider about your experiences and any concerns. Recovery can be a gradual process, and it’s important to stay patient and hopeful. Good luck, and I hope you find what works best for you soon!
