Grace

So my husband will be getting deployed in January’s he won’t be back for at least nine months. I’m currently five weeks pregnant. My husband likes when he is gone for me to send him pictures and videos of me masturbating but as my faith has grown I’m a little concerned with how God feels about me masturbating... even if my husband approves. I guess what I’m asking is if anyone has read anything in the Bible referring to this? I know it says thinking of anyone but your spouse in a sexual way is a sin but idk about masturbating?
