BIG DICK?!?? Help me 😭

So I recently left an abusive relationship and have met this new amazing boy who spoils me and is so sweet. He was happy to wait for me to be more comfortable before we did anything super sexual and after meeting his parents and having it go so well I decided I was ready.

Of course he told me we might have a bit of trouble because he was on the larger size but I just assumed that was just his boy ego talking but GIRL no it is huge

I nearly had a heart attack! He was super supportive and talked me out of a near panic attack and I just ended up giving him a blowjob but does anyone have this problem with their partners? And if so what was the steps you took to work yourself up for it? He is only my second ever sexual partner but I like him so much and I really want to be more intimate with him.
