I had a relationship with a gentleman with the same condition as yourself, we were together before and after he had his circumcision
It took him and me quite a while to adapt to the new organ, it was more an emotional thing for my partner. He had been a late starter and because of his problem had resigned himself to being unable to have a wife and children. It was only at my suggestion he actually went to the Doctor.
I guess I am saying is give your mind time to adjust to your new and exciting future, before your operations your body was probably frustrated at not be able to full erect your penis, but now it is doing it you're fulfilled; not sexual fulfillment but more to do with feeling like a complete man.
Just give yourself time
