Would this be a weird thing to do?

I've been single a long time. One of my cousins introduced me to their friend at Thanksgiving. He's deaf so he had a notepad with him to talk. Me and him were having conversations back to back constantly through the notepad and I honestly really like him. I feel like we really hit it off. We've been texting since Thursday and I kind of want to learn to ask him out through sign language. Would that be weird?
