My fwb wants me to do it without a condom

I met this girl online, and we've been talking for last 3-4 months. During all this time, she mentioned it many times that she has a crush on me and wants us to date. But i maintained my stance that I've no such feelings, and let's just be friends. She was fine by it and we still talk with the same energy. Now we've decided to take it further and make it a FWB thing. I'm going to meet her soon and we'll be having sex on our first meet. Now, she wants me to do it without a condom, saying that she likes it raw. But I've never done it without a condom, I'm very cautious in that. So what should i do, try it with no condom or try to convince her for me using one?
