I want to second @surftohealth88's comments about how long it can take the nerves to recover after the surgery. I wish I'd have kept a journal as it's hard to remember the details of the journey. Looking at my old posts, at 4 months I was 65% back, and barely firm enough to be able to have (very marginal) intercourse with my wife. That's with being on daily 5mg tadalafil and also using 100mg sildenafil an hour before intercourse (on an empty stomach). I consider I regained full pre-surgery capability about 14+ months after surgery. But make no mistake, progress for me seemed painfully slow and there were many times when I doubted I'd ever regain pre-surgery capability. At this point I continue to take the 5mg daily tadalafil and also still use 100mg sildenafil an hour before we want to have intercourse. I'll talk to my doctor about it at the next visit, and I'm not a medical professional so I may well be wrong, but I'm planning to stay on both pills indefinitely. But who knows, maybe things will get better and I won't need them in the future. At this point, I'm just very thankful they work for me. I should also mention that this whole time I've been exercising regularly, eating well, taking vitamin and magnesium supplements, and basically trying to give my body every chance to recover the nerve function. Was all that necessary, I certainly don't really know, but my personal belief is that it's all helped. Best wishes.
