HUGE penis helppp

So, there's a really hot guy that I've been into for somewhere around four years. He messaged me the other day and it got pretty heated. We descused hooking up. He isn't much of a relationship type, and honestly I don't think I would want that with him (one night stand or even fwb would be amazing!😏). We sent inappropriate pictures to each other 😬 and let me tell you. He has a HUGR penis. Like, intimidatingly gigantic. Like, when guys lie and say they have a 12 inch penis, this guy wouldn't be lying. I'm pretty new to not being a virgin too so I'm terrified. My ex was pretty average and he was the only person I've been with, but that's besides the point. Any suggestions on taking it well and advise on how to be more sexy and less passionate? I like it rough I just wouldn't know the first thing about approaching it with someone I'm not committed to. I really don't want to screw this up lol! Helpp!
