HELP ME

My boyfriend wants booty pics and I’ll gladly send them, however I’m super insecure and want to make sure I take a great picture. This might be a weird question but I need advice on how to take it without showing extra flubber from my tummy or legs. I also need advice on do I take it in underwear? Lingerie? Leggings? I’m a fairly tame and not very sexual person because

of how insecure I am but I want to be more sexual with him because he’s literally so damn hot. All the advice will help!!!
