How to I get my burt to open up???

Sarah

I am hesitant to have anal but I am also very intrigued. There have been a few times i think my husband has really wanted to and I would have been open to it but he knows my hesitations so hasn't asked and neither did I. Id like to try something new with him, and a finger feels good but I dont know how to get it to open up enough for his huge dick. Any advice or tips?
