I need advice 😬

So me and my boyfriend have been dating for 11 months and he has asked me to send him nudes. I have my doubts though especially because of what everybody thinks about which is screenshots or then being showed or sent to other people but I expressed that concern to him and he made it clear that wouldn’t happen but, I’m also not sure I want him to see my body. I am not very confident in my naked body and I’m afraid if I show him he will think I’m ugly. What do you think I should do?
