David is a lawyer practicing with a large firm. One of his largest clients, T.W. has requested David to act on behalf of T.W., including both T.W.'s corporate matters and T.W.'s separation and divorce. During the proceedings around the separation and divorce, David and T.W. noticed a developing sexual attraction between them.

One night last week after a particularly rough day in court, David and T.W. agreed to meet for dinner. Over dinner and subsequent drinks, the two began making overt sexual advances toward each other, and ultimately ended up at the home of T.W., where they had a sexual encounter.

Since last week, David and T.W. have decided to become involved in a sexual relationship.

Are there any issues with David continuing to represent T.W.?
