The last few commenters have given no advice. The actual advice I have been given I greatly appreciated.
I'm not sure why some continue to comment on my post just to tell me to listen to someone else.
There is technically advice in reminding someone that someone else's posts to do have value, or more value than you might think. Since this is a community of people who are in all stages of their poly journey, their advice will likely be from that viewpoint. Equally, the members of this forum will and do like to make clear, as Vis said, 'this isn't a blow sunshine up your ass forum'. That is actually very helpful to know. How helpful is only receiving feedback that 'makes everything sound good'? You should want powerful, real, deep, and thoughtful feedback that helps you question and answer those questions about where you really stand in your journey, who you really are, what you really want, what you really need, and what your partners really want and need and are telling you.
I read your first few posts and "couple is primary" "veto Power" etc, can give a lot of poly people the hackles right out the gate, because many many poly people have been treated poorly as a secondary, vetoed, tossed away when it wasn't convenient for the 'primary', and that type of thing is considered very unethical in polyamory. Many have been hurt because of that.
All people you choose to get involved with are important, have feelings, have boundaries, have a voice.
So keep in mind that while you might not like or agree with all the advice given, each person is coming from their own experiences and perspective as well.

How do I make my husband feel he is still important to me during our ..times, and how do I approach the relationship idea?
You can't make your husband feel anything. Treat your husband like he's important to you, ask and meet his needs, and let him work on his own security on his own. He owns his emotions. He owns his communication.
If he saids "I need you to make me feel important" how is that helpful.
He should say "I need to have quality alone time with you. I need to have one-on-one sex. I need to go on dates. I need X" and you can reply with which of those needs you are comfortable with fulfilling.
And that's how you help him to feel important.
Poly is largely communication.
