I have my own theory on it. Nepali behuli why do u say u don't enjoy sex because your hubby has uncurcumcised penis? I think before marriage you have tried circumcised that's why or this might be some guy who is ashamed to ask us how to make it circumcised. When I posted I fell in love with a stripper, lots of people called troll so you might be telling the truth just like I did. 
       The best solution might be let him eat your vagina that way u can feel good. Then suck his penis n play with your hand like masturbate his penis n try to roll down the skin layer gently. Keep doing that months n months n i believe your hubby's penis will be circumcised later. 
         When I was a kid I used to clean penis as i used to see white thick powdery stuff within my skin so I used to scroll it down all the time while taking shower n now I have circumcised. At first I was scared what did I do? Why was their no skin on my penis head? I was worried. Will it affect my masculinity to produce children this n that. But in western culture circumcised is considered hygienic. 
          Further it might be his small penis who is not giving u a satisfaction. He might be lack of fructose acid as his erection is not projectile n 90 degree. Get him some pills to increase his penis. You can go to pornstar Ron Jeremy's site n find out how to increase penis size.
