How to draw a line between being too needy/clingy and expressing what you need?

I feel like I’m too needy in regards to affection and romance. I can be clingy too.

Though I have a simple rule in mind, I don’t disturb him during his time at work, just regular checking up on him, and I don’t disturb him when he’s spending time with his friends and family. I’m only as included as he wants me to be. I neither indulge myself nor ask him to spend less time with others and more time with me.

In this regard, I feel like I give enough space and freedom with genuinely no complaints. But then comes the time he spends with me. That’s the time I want ALL of him! Doesn’t matter if it’s just the little time before bed I get, after a long day of him spending time with others. Quality>>>Quantity

The time with me, I want all the attention, affection, cuddles, kisses, groping, everything!! No distractions, no mobiles, no lack of interest! As if I’m the only thing that matters.

I know that sounds a lot and even kinda selfish/narcissistic but I do the same for him. The time with him, is only for and about him!

Now, that’s not what happens! After a tiring day, he goes to bed and wants to be left alone. But he’s very understanding too, I’m sure he would do more if I say so. But I don’t want to come off as needy or put him under a sense of obligation, where he does it as a duty. how do I draw a line in between?

He used to be very generous in his affections before but that has changed after marriage. Shall I take it as a sign that he’s not interested anymore in it and stop being needy? Or shall I say him what I need and risk burdening him with a duty?
