Sexy pictures for boyfriend tips??

So I rarely ever send my boyfriend nudes or sexy pictures because one I’m not confident in my body and two I don’t know many poses or how to take the pictures. He doesn’t ask for them anymore because he pretty much knows the answer but I want to take some for him and randomly surprise him with them because I haven’t done it in so long but I don’t want the same old straight forward nudes. If anyone has any tips or good poses and how to take them with your phone I would appreciate it so much. Thanks!!
