Anal during pregnancy

Natalie
So I'm 38 weeks pregnant and I'm getting induced on Tuesday but I don't want to get the scraping of my white membrane in my vaga so I was thinking what if I let my husband do anal on me with a toy and we have sex at the same time would be better. Maybe it'll make me dilate. I don't like anal cause it hurts. Any suggestions about anal? I've never used a toy on my anal either. What's the best lube as well? Need help ASAP!!!
