Damaged prostate nerves

Great to find a forum on prostate issues. I've got damaged nerves around my prostate after a protectomy procedure, resulting in a permanent colostomy. Procedure was due to extensive Crohns, but I was at high risk of getting bowel cancer due to a stricture. I was warned that I would possibly have ED. Thankfully, this was not the case but I find it harder [sic] to get an erection. I have retrograde edjucation, essentially meaning dry cum and a loss of sexual satisfaction. Its a little inhibiting but something I've learned to live with.
