I'm a anti vaxxer and I got COVID. Do I suck dick for the antibodies?

I'm bad with titles. I'm bad with people. But I got COVID and heard that getting plasma from someone with the antibodies can help you get better. I got mild symptoms and am pretty sure I have the antibodies. I am an attractive girl who can easily manipulate people but I don't know if this guy is interested or not so how do I approach this? He's really smart and the only person I've met that I can't outsmart. So here's the deal. How do I suck his dick for the antibodies? We are adults by the way.
