Online dating alert

Hey beautiful people, I met a guy online and we met once . We made up in the car but didn’t do the deed as both agreed it was too soon. We needed time. Anyway, why am I here? Am here to ask if you may advise me on what to do , he wants me to send him nude nude skin clear “p$$$” and I told him I have never done that but he keeps insisting despite me backing off. I did send a very soft picture with a panty on without my face and just me in bras without face too. He insists and I feel not safe to trust him with my nudes . The other thing is I have never sent nudes to anyone . Should I be worried ? He did send me his nudes with face and whole body and one or two with his nakedness. He insists my p$$$ turns him on, when we met he only fingered me and licked my juice from his fingers . But he wants photos. What do people find in nudes . Should I trust him to continue our relationship?
