How to get a man to desire you

Like the title says, I’m trying to get my husband to desire me. I what things could I try? I give him blowjobs every time we have sex because he loves them. We’re both have put on weight and his penis is on the smaller side so we’ve been limited to doggy, missionary, and I usually ride him. I don’t have lingerie that fits and it’s not really in the budget so I’d feel guilty to buy any (he’s never seem excited when I wore it anyway)

What things could I do to get him to really desire me? I’ve never felt that he’s ever desired me especially now that I’ve put on baby weight and I just want to feel that 💕
