Recently my husband and I tried anal for the first time, we have only tried it twice so far. Both times we started out vaginally and slowly eased into anal. With a condom and a lot of lube, mind you. Now my husband wants to try anal without a condom because he feels the condom took away from the full sensation. As we are in a monogamous marriage and have been for the entirety of our relationship I am not worried about and STD. Is there anything that should prevent us from going without protection?
