I am a 45, when I have an erection, the shaft of the penis is hard but the glans is soft, I have a main vein going along the top of the penis which goes off to the right ( not straight ). I have had problems with a tight foreskin in my 30's and had a circumcision to correct this.

I think the glans should be hard in an erection, is this true?
Does the top vein supply the blood to the glans, to make it hard.


Thanks for your help.
