So let's put it like this.
Most men enjoy both anal and oral, but they have a preference for one or the other. But they still like both, or they don't really care and they "adapt" to the partner.
Then there are the sides, who finally have a name and the possibility to indicate their preference on dating apps! There is an enormous amount of men who do not enjoy anal, both as top and as a bottom. You won't have difficulties finding someone who has your same sexual fantasies, and who adores blowjobs or any other type of non-anal sex.
And then there's me. I'm incredibly into anal sex, while I don't care so much about oral. I prefer eating ass to having my dick sucked, because... You know, rimming is a form of anal play, blowjobs are not. I don't get turned on much by a blowjob if there is no assplay, even as just a fantasy or a possible thing happening in the future. Most guys don't have such a love for anal sex as I do.
So yeah, me and you, the opposite extremes in the spectrum. Very likely not a match sexually

But I think it's a bit unfair to call it a "dealbreaker". Both my and your sexual preferences are totally valid. And in the end, we will never match with 100% of people, sexually.
In the end, I think if I asked the specular question ("would it be a dealbreaker for you, as a sexual partner, if I like fucking your ass every day?") I would probably have a majority of people saying "geez, that's a lot! I can't be bothered douching every day" "I like anal but not every day" and so on. And then a minority of people who will say "oh fuck yeah, finally someone who likes it just as much as I do".
Same goes for you, I think many guys would say "are you sure? Like, not even anal once in a while?" and then some would go "oh finally I don't have to pretend I like anal, let's suck each other's cocks into oblivion". Filtering guys by sexual role on dating apps is your best friend
