Just try to get ready or wear something nice/sexy that you feel good and do something to your husband he likes .l Like my husband loves getting oral sex that makes him wanna get up even when his super tired or sleepy. Also ask him why you guys haven't had any sex lately communication is the key as we'll and I'm 30 weeks pregnant and don't feel so secure about my body either but even husband babe your pregnant a few more weeks and it would be over so just be patient and love your body
Go out, buy some lingerie, get your hair done and make up done. Wait for him all sexy like on the bed, and see what happens. It seems like a good idea, if I was in your situation this is what i would try.
If yuu feel the drive is gone... not to be nasty but aye try oral yuu neva knw wat could happen next.... or if your more into sex yuu try startin off see if hes interested!!!
