I have an asexual friend who constantly makes diddy jokes so I think you're good in that regard

I have a few ace friends that write and draw NSFW art 24/7. They appreciate the form, it just doesn't do anything for them. Similarly, I also know a ton of lesbians that salivate at yaoi/mlm but have no attraction to men

do I still count as 100% asexual even if if I find that stuff funny and make jokes?

If someone is homosexual and laughs about heterosexual jokes, is the person then bisexual? And how many laughs about those jokes are needed, so that the homosexuality gets transformed into bisexuality? And this is comparable to asexuality, what you tell me asexual jokes and I find them funny. It wouldn't change my sexuality or it wouldn't change your sexuality if you laugh about sexual jokes. I mean, are asexual people not able to laugh about things they have no interest, like sexuality? Its not like they lost their humor.

Everything is fine with you. If you say, that you are asexual, then you are. Laugh about whatever you want. "Weird" is subjective. And I think there is absolute nothing weird about it :)

A decent number of ace people I know make more sex jokes than most other people I know

How is sex not even more hilarious from the outside looking in? What are these clowns up to and why? They actually like doing those gross fucking things to each other and having them done upon themselves!?

Some things might be common, but there’s no such thing as “normal”. Life is short, enjoy it however you can.

You couldn't possibly be weird for such a thing, there's no "normal" to begin with aside from the exploitative and patriarchal relationships encouraged by capital. Feel yourself, enjoy yourself, don't worry about labels and being a "real asexual", whatever that means. You valid! These labels are here to find community with people with similar experiences and often include a wide variety of ppl with seperate interpretations of what it means to be asexual, trans, queer or otherwise, sometimes in contradiction with each other. But they're just words to describe ourselves, when the only truth is the experiences you've had that have led you to describe yourself as such and the usefulness you find within.
