Pls help, it’s driving me crazy

No, Not really
After all, Attraction doesn't know blood either

If you're worried about the stereotype of mutant babies, Don't worry about it, It's doesn't actually happen, Well, If you're healthy, That is.

Though, I'm not exactly sure where you live, Because half of the planet (Kinda 50/50) makes it illegal

Been there.. "Wrong" and "weird" are very subjective categories, so it all depends on how you see it. Do they know? If so, how do they feel about it? In the end it comes down to just you two. If you both want it just go for it. And for sanity's sake you might want to decide whether to tell people who might not be ok with it.

I don't think incest is ok tbh.

Depends on age and blood level-

Like nah if it's your Cousin then I don't think it's that bad-
In the Bible people married distant family and cousins all the time-

As long as it's not like- your sister or brother-
I don't see an issue

Love is love, you can’t control it. You should just tell them how you feel, be very specific, if you’re the one that said you were ace, tell them that. Don’t worry about what others think, it’ll just bring you down. Without marrying cousins and such, the human race would be extinct, even today it’s common for people who aren’t related be genetically cousins and not know it and get married and such. Good luck with telling them!

i lost my virginity to one , not my fault my mom never told me we were related :T

I would say that these feelings are not wrong (nobody controls their emotions) but it’s definitely abnormal. Related people aren’t legally allowed to get married, because it’s easy for undesirable genetical mutations that cripple life forms to pop up.
The first thing you should do is talk to someone, which is exactly what you’re doing by posting this, good job.
I don’t know everything about this, so I’m going to wait until one of the server’s smarter members to see this and give you a more detailed answer.
Again, good on you for posting this, this is exactly what you should do if you’re confused.

About the emotion control thing, Saying "nobody can control it", People CAN actually do that
Just wanted to point that out,

Yes I know, I’m ace, but not aromantic, I have no interest in anything like that, I just have a very strong romantic attraction

You're the one who made this post?
If so, Romance is cool for all, Pretty sure it's legal for all too

Huh, thought it was illegal everywhere. Like I said, I’m not an expert on this.

If it’s legal, then it should be fine for you two to get together if they consent to it.
