My Husband is becoming something else when it comes to Sex

My name is Uche, my problem is my husband. Before we got married, he was very decent and a gentleman. Since we got married, however, he has turned into what can best be described as a s*x freak.

He likes to have s*xual intercourse in unusual and perverted ways. Although we have a very comfortable bed in our bedroom but he likes taking me to other places during action...

He asks me to suck him. I want to please him in this, but his "banana" is so large, it always makes me gag! I never ask him to do anything abnormal, so why has he turned into something I now fear? It has got to a point where I hate making love with him. I have even thought of running away
