Hi Numbness41
I have just read about what has happened to you. We all have made mistake in our life and its how we deal with them that makes us who we are today. It saddens me that you have lost a part of you that will change your life. In society if you lose a limb or finger you can still carry on with a change , and still have a normal sexual relationship. When you lose a penis it will be extremely hard and it sounds like your girlfriend is there for you, supporting you.
Remember that Love is not just sexual. You can still please her with your hands, fingers, and orally, she still loves you and wants to be with you. I can not imagine what your going through and the feelings that you are having but do not give up, there are many toys out there that are realistic, talk to her and be honest. I believe she loves you and will be there for you.
This is going to be a healing period for you and the physical part will be the easiest but the psychological part may take longer. Everyone is different in how they take a bad situation and turn it around. I have read the posts and the replies you have given, you are incredible strong on how you are handling this, I commend you for telling us your story and what has happened. Remember your attributes and values that you have, do not underestimate what you have to give, do not sell yourself short.
A penis does not define who you are. There are men in this world that are born with micro penis or smaller, they do the best they can with women who have been with bigger penises but they are still with them, they are with them for more than their penis size. There is a guy by the name of Andrew Wardle who was born with out a penis has slept with over a 100 women.
You have a lot to give do not forget that Numbness, you have suffered a tragedy and you are dealing with it in your own way, do not push your girlfriend away, she is there for you. You are strong ,you can do it, just telling us your story and what has happened tells me you are strong, not having a penis will make you better in other ways with your girlfriend.
I can not comprehend what you are going through but I feel for you and try to stay positive, be with people that are there for you. Only you can decide your future, healing will take time .
