need advice! help please

I gave birth to my 4th child on Feb 24. I am 24, been married for 5 years to the love of my life. I weigh 115 pounds and stand 5'4. I have cellulite on the back of my thighs which causes me to cover myself as much as possible I'm very embarrassed about it. I want to feel sexy again. I just feel very uncomfortable with myself. I had all kinds of sexual thoughts and such that I anticipate to do in the bedroom but then it's naked time and I get really scared he will think I'm gross looking or something. he has never said a foul word to me, I just don't want to let him down or think I'm letting myself go or something. he will ask for a strip tease or stuff like that and im just literally clueless. what do i do??? please don't be mean. my mother body shamed me my whole life and I have serious confidence and self-esteem issues.

Also, could yall offer any foreplay tips/sexual tips? my 6 week checkup is Tuesday and I would really like if I can bring something new to the table when the time comes.
