I'm not attractive anymore?

So my husband and I have been together since April 2017 and married since September 2017. We have 4 kids and one on the way. (My daughter from previous relationship, his son & daughter from previous relationship, our baby boy together) and I'm currently 21+6 with our last babygirl. I admit I havent been super sexual this pregnancy. Pregnancy in itself has worn me out considering I just had our son last november. I havent felt the best about my body, but he's not making it better. All he ever wants is head or a hand job now. (My 😻 has never been bad) he used to be on me ALL the time, but as of recently(last few months) thats all he wants. Granted we've had our ups and downs thiese past few months. He even went so far as to tell me, he wasn't wanting to have sex because we were arguing a lot and it turned him off. (Understandable)

BUT,

We've been so good since we really say down and talked (or so I thought😳😭)

Today I started rubbing on him and then asked if he took a shower...(so I could do the deed(head) and my ultimate goal was SEX. He tells me as I'm going, I just want some head and to relax. 🤕🔫

Like WTF.....

So I just keep rubbing him and that shit turned me off completly. Like I was barley rubbing him to the point of him going "limp"....

My feelings are so damn hurt and i dont know what to do. 😭😭😭 I'm crushed and wondering all types of things in my head. Me knowing my husband he is a VERY sexual person.

I don't want to ask him if hes "into" someone else literally, because it will start an argument and I don't want to ask if he's still into me or attracted to me because I don't want to seem insecure. I just don't know what to do.

ANY ADVICE LADIES ?! 😒😔
