Did I mess things up?

So I was talking to a guy I like , we were talking about sex. He said it’s his fantasy to give me head , which he has done before.
He said it makes him get more attached and feel a bond with someone he likes.
I told him we could bond in other ways and he said yes but doing physical stuff is quicker.
I then told him if he just wanted someone to have sex with he could just say it and he said but he wasn’t insisting on sex or trying to force me. That he was just saying what his fantasies are.
He then says smh and goes offline.
So I thought he got mad and sent him a bunch of texts and was trying to explain why I was asking and saying I didn’t want him to get mad and he shouldn’t get mad blah blah. Also called twice and he didn’t pick up.
So I sent a goodnight text and stuff.
This is very much unlike me but I kind of get nervous with him and it makes me awkward so I was getting comfortable and didn’t wanna go back to the awkwardness so I panicked and sent all those texts.
He calls back just immediately and tells me he wasn’t mad and he had just gone downstairs to get some food and got back and saw my texts that he is not even mad one bit.
I then asked if we could talk about it more, so I tell him that I’m just not ready for sex and want to take it slow.
He says he knows cause I’ve said it before and he would never force me to do it or anything. That he perfectly understands and he’ll want my consent but he was just telling me his fantasies. I then tell him that I don’t mind that but I still won’t have sex that’s why I’m skeptical about it.
He says it’s okay and understands.
Awkward silence and in a bid to change the topic I then tell him he scares me sometimes but not in a bad way but then the phone got cut off .
I was basically trying to tell him about my nervousness and maybe we could talk about it and i’d get more comfortable
He texts me to tell me his airtime was off.
So he went to bed.

So now I’m panicking again cause I feel like I messed things up, it’s been going pretty good between us but I think this conversation definitely messes things up and just worried he might now was take things extra slow or just not text me again.
Did I mess things up?
The whole triple texting and calling cause I panicked and thought he was mad.
And just constantly repeating that I won’t have sex even when he had already said he understands.
And then blurting out that he scares me sometimes.
I mean I think it’s all too much and I don’t know what he thinks now.
Should I maybe text or call him again later and have a normal conversation without bringing any of it up or do I see if he’ll contact me?
