It is natural for him to want to have sex, most people do at least some of the time. That is not meant as a critisism of you just an observation.

What is it that you are asking for in this thread? Do you want to feel more sexual and get ideas or are you wanting to see if others feel similarly. I think it is natural for sex to become less of a prioity in a long term relationship if it is not maintained but it doesn't have to be.

Do you know where your dislike for nakedness and sex in general is comming from.

You say that you come up with ideas sometimes but not when you are having sex so maybe keep hold of these for those times and express them then.

Good luck. tt
