Will my body ever be the same?

Today marks 40 wks of pregnancy and I've gained 20 lbs. My husband has been more then supportive threw my entire pregnancy, but I can't help but get the feeling that he won't want me sexually and physically after I have our son. His sex drive hasn't changed at all, if it has its only increased. He tells me I'm beautiful and sexy and everything else but sometimes we're out and he checks out other girls. I understand he's a guy and he's gonna look, but I just feel bad because I'm not that. I'm not what I used to be and I really want my body back. He tells me he loves me reguardless but hopes I don't let myself go after mijo, and I hope I don't either. Point is, how hard was it for y'all to get yalls body back to pre pregnancy?
