What Causes Erectile Dysfunction Post Circumcision?

Question: Hi Doctor,

I am 32 years old virgin. I have recently got circumcised as I was previously suffering from tight Phimosis. I can now see my glans which I had never seen before.
Because I had tight phimosis, my erections always had a curve. Now that I am circumcised I had expected the curve to go away, but it seems that my penis has gotten deformed over the years.
Another issue is that whenever I feel horny, my penis does get hard but it does not move up. So if I am standing, my hard penis will still act under the effect of gravity (very slightly at an angle of 1 or 2 degrees, it goes up). My penis loses erection if I try to move it up using my hands.
I am due to be married in next 3-4 months and this this is highly worrying me.
Lastly, though unrelated, I dont feel aroused by thoughts vagina. I get turned on by other aspects of girls body except vagina. This may due to the fact that phimosis in early years never let me develop the feeling of inserting and stroking. I masturbate - not by stroking forcefully but by light caressing and stroking

Please help me in whatever way -
PS: I am not XXXXXXX by any means
