Most Helpful Girl
Its the beauty of a life being created(and personaly I find it a vile process,the birthing and all but whateve) I doubt it has anything to do physically with the woman beyond what her body is capable of doing.
But I think your taking it a little to much to heart you might want to have a one on one with your boyfriend and explain how you feel about this because it seems to be bringing you a lot of negative stress about something you no longer can controll.
I have no idea if you two have been dating long or if he even knows you had a hysterectomy I will assume he does know all this and if he doesn't its probably time you tell him and your feelings about it as well.
There is always adoption wich I always think is more a beatifull act than making a baby oneself. There are a lot of children out there who need love.
You really need to talk to your Boyfriend befor to much longer because its just going to eat at you untill you hear what e has to say about it.
