What do you mean by "his not attentive to my needs." Have you asked for what you need and he doesn't do anything, or he did it in the past and you haven't said anything, thinking he should do it of his own accord?
If you don't have friends, see if there are any Mommy and Me groups. If your five year old has a special friend at school, you could ask the parent if a playdate could be set up. Those connections will also be good for posibly exchanging babysitting hours so that you can go on dates with your husband, or to ask if they know of anybody who they can refer as a babysitter.
At home, keep your physical connection alive by sometimes suggesting giving each other a foot rub or back rub while you listen to music or watch TV. When apart, send a sweet text, telling him you miss him. Pick up a special treat he likes when you're at the store. When you put in effort, he will hopefully begin putting in more effort himself.
If things have gotten stale in the bedroom, try new things like role playing, new positions.
Make sure you avoid blaming language. Instead of "You never do XYZ. Why can't we ever XYZ." It's better to say things like, "I'd like it if we XYZ. I think it'd be fun if we try XYZ."
It's also important to miss each other. Giving each other the gift of free time alone is good for the soul. He can stay home with the kids while you have a hobby or time with a girl friend once a week, and you can give him the same time to himself.
Good luck and let us know how it goes.
