No more sex... help

Okay so, I have an 11 week old and ever since I got the green light to have sex again it just hasn’t been happening.. I feel as if I don’t bring up having sex with my husband we simply won’t have it. He much rather come to bed and just jack off while watching porn. I am literally next to him and he would rather jack off. It’s making me feel unwanted and like he’s seeing someone else. I am not the one to beg a man to be with me. I’ve brought it up several times and his response is just “okay let’s do it” nooo that’s not the point, the point is you should want to want me! I’m getting fed up. I am sexually frustrated. And quite possibly I am considering having sexual relations with someone else.. I don’t want to cheat, it’s not in me, but I feel it coming.. he makes me feel ugly especially after my body changing because of the baby. I tell myself it’s ok, it won’t be forever. I can work out the weight I gained and I can change my look, but why do I have to do that to feel beautiful? I don’t know what to do and I need suggestions if anyone reads this. How would you feel?
