Why doesn't my fiance want to have more ????

I've been with my fiance for 2 years now and our ual relationship really needs some work. He says he is very attracted to me and he loves me very much, although sometimes it feels like the kind of love you would give your puppy. He is a bosnian refugee and didn't have a girlfriend or for 9 years, however did watch a lot of . I umed this could be the reason for the very distant, and not so often , but after two years and me explaining my feelings nothing has changed. Im beginning to wonder if he is really attracted to the oppisite . I have asked him and He said "no" but i never see him pay attention to another women , only men. I know he is very loyal to me , but I dont want to give up my life, knowing that I will never have that special deep pion love / .Please if you have any real advice, let me know.
