Acute pain in genital area. Infertility?

I am married for the last two years. I did not have any physical intimacy with any lady before that. But after marriage, I felt absolutely no urge for sex. The process was done mechanically which did not give any pleasure to me. I use lox 2% jelly for smoothing the procedure as doing that without the jelly leads to acute pain. The problem took its peak for the last seven days. Since one week, after applying jelly, whenever I am pressing it to the vagina, the foreskin of my penis is pulling back by two three inches and inner flesh is getting exposed heavily. It is coming to direct contact with the vaginal fluid, friction is happening and all these are leading to acute pain in my penis. The foreskin never used to pull back and the inner flesh never used to expose before. In the last seven days, it happened thrice. I am extremely worried. During urination also, the pain is pinching from inside. What should I do now? Will I be able normal again? Is it leading to infertility? Please help.
