HELP: "My Husband's Manhood Is Too Big And Long"

We got married three months ago. Our problem is my husband’s huge anatomy. It is not only huge but long. I never saw it before we got married.

Lovemaking is a nightmare for me. He would keep going at it for more than 30minutes before he finally ejaculates.
What can I do to make him soft because it is usually very hard?
