How can I prevent the intimacy issues I am having by my partner sleeping in bed with his 8 yr old daughter?

there is more than one issue here, and I wonder which one worries you more. It is legitimate for you to feel neglected, because your partner sleeps with someone other than yourself. That is fine, partners come with strings attached, and we must love them warts and all.
The second issue concerns the father-daugher relationship. Physical contact between parent and child is a good thing to have, and I'm not assuming he would be sexually harming his daughter. They may have a good bond, but he will have to let go. Within a few years, the daugher will start developing, and will have a natural need to be alone.
My advice: prepare your partner for the "loss" he will experience when his daughter starts to grow up.

uhmmm, wow.. Get her her own bed if thats the problem, she's far too old to be in bed with him on a regular basis thats simply inappropriate. If lack of a bed isn't the issue, I think there must be something really wrong there.. Really wrong.

Yeah, have him sleep with you instead.

You may have to explain to her that adults need their space and children need to learn confidence. Do so in a polite and simple way...and good luck.

i had to start getting his daughter to sleep by herself. it was not easy because she has never slept alone. she has a bed at her house but sleeps with her mother. i have a hard time sleeping even with my daughter. until we get a bed she sleeps on our big comfy couch. my daughter gives up her bed to keep her comany on the otherside of the couch. we had to start locking the bedroom door because she just walks in. we are not always decent so that is one issue too. its taken time for her to get use to. i always check on her after i know she went back to the couch. sometimes she said she had nightmares, but she seemed fine. i believe a child at that age does need her own space and so do the parents. it causes too much dependance and insecurity when they have to be in there. they need to slowly grow from being sepperated. it will take time and some crying but dont give in, she is happier . i felt so mean and selfish. that will pass.

i think he has the intimacy problems - maybe with his daughter???

By 8 years old a child should be sleeping in their own bed.

If she is in the bed, you should sleep in hers.

If she was my kid, first of all I'd be freaked out at her dad letting her sleep with him, but if I found out his girlfriend was also in the bed I'd seriously looking at custody issues. But that's just me.

Funny, if a mother was sleeping in bed with her 8 year old would people feel the same? My son and I sleep sometimes in the same bed, or on the couch together. Both of my teenagers went away to college this August and he is having a rough time of it. I see nothing wrong with him sleeping with me.

Some times you need to be brutal get the job done. Start to fondle the guy, do it all night long.
I'm sure she will be in her own bed soon.
Or, she will learn some facts of life really soon.

I dont like the sound of this....she's 8 she can sleep without her dad surely? >:(

You simply can't do things in front of a child.

Buy him a DOG.

that is just so wrong in so many ways

See someone
These issues are irrational unless you don't love him or have no sex drive where if ither you should probaly know

Where is his daughter's mother??????

Its not your issue, its his. Eight year old girls should have their own beds and so should their fathers!

"His" 8 year old daughter...??
Sit him down and ask him straight out , Why he is avoiding being intimate with you. Something is wrong and he should address it. Whatever it is he needs to find more appropiate sleeping arrangements. A kid crawling in to their parent's bed on occasion is one thing. Every night a parent sleeping with a child instead of their mate is a avoidance issue because obviously you are not getting the intimacy you desire.
