My husband eagerly desires to penetrate my anus and demean me sexually

My husband has been craving to penetrate my anus for quite some time now. He's always trying to demean me sexually, and I don't know why. He's a big fan of anal play, and he's been begging me to let him fuck me anally. I'm not against it, but I don't want to risk getting pregnant. He's always talking about how much he wants to fill me up with his big cock and make me his little whore. He's been trying to convince me to let him fuck me in the ass for months now, but I'm not sure if I want to give in. He's always on his knees, begging me to let him do it. He's been trying to get me to suck his cock too, but I'm not really into that. He's always asking me to suck his big, fat cock and give him a blowjob.
