Have a hard time giving my bf head

I’m 12 weeks pregnant and our sex life has slowed down with me being anxious about miscarriage and just feeling like shit most of the time. He’s been extremely understanding though as we’ve been trying to get pregnant for a few years. Anyway, I still try my hardest to satisfy him. But giving him head has always been really difficult because his dick is seriously HUGE. Not even trying to over exaggerate. It’s thick and long (9 inches when SOFT - we’ve measured) and I have a small mouth. What can I do to make giving him head easier/better?! 😩

Thanks for the suggestions everyone. It’s difficult lol. I do already lick/suck his balls and he loves that, and I’ve actually suggested a pocket pussy but he says absolutely not. Ugh!
