Lingerie#sex#

We have a 1 year old baby boy. Me and the baby was away from my husband for two months vacation. We are going back in three days. I want to have great sex. I'm a little shy type. I don't think I have the great body. I want to have a big butt for my husband, because I know he's going to love it more if I had one. I want to make our sex great since we see each other after a long time. I want to know good tips on how to do it, want to wear a sexy looking undies. But I haven't anyday since I feel so shy and insecure.

Please give me some tips of giving him a great pleasure and on doing some sexy lingerie( I always worry Bout not having a big butt, I have lost the things I had due to breastfeeding the baby)
