Like others OP, I feel really concerned about your husband's behaviour, approach to sexual activity with you, and his stance of teacher/all knowing guru when you are by it's very nature the expert on your own body.
Some questions I have:
Do you ever independently feel like you want to have sex or be touched sexually?
Have you ever had an orgasm alone or with a partner?
Some statements that may be useful in working things out:
Arousal is made up of two parts - physical and psychological. Being aroused is when BOTH are active.
It is normal to not return to the same hormonal and sexual desire baseline after having kids.
This is especially true if you do the vast majority of the parenting and housework.
Peoples baseline levels of sexual desire vary across individuals and across time. You having lower sexual desire than your husband does not mean it's true that you just didn't/don't recognise it.
Sometimes people raised in purity cultures or who have experienced sexual abuse associate arousal with shame, fear and pain. This can impact on them being able to experience and share their sexuality.
Bodies react to physical touch even without psychological arousal. Even people experiencing terrifying assaults have reported this. That does not mean you are consenting or that you are "aroused" overall. Your husband is wrong to believe that your body reacting means you are aroused overall.
In healthy relationships, people do sometimes think "I'm going to give it a go and see if I get into it" when they are not in the psychological headspace for arousal. The difference between your situation and this is that the control is in the hands of the person who isn't sure. If they don't want to, it doesn't happen, if they try and aren't getting into the psychological headspace, they stop. The other person just accepts this and does sulk or get all hurt.
Unless you have a tickle fetish, tickly isn't the same as arousing.
Sulking and pouting and being hurt or arsey if the other person isn't up for sex is coercive and sexually abusive behaviour.
All of this makes me feel so angry for you. He is not your mind reader. He does not know your body better than you do. You said I do not feel aroused this morning and he said I think you are wrong and will act on my beliefs not yours. That is coercive and controlling behaviour and unacceptable.
