It can be psychological. A gay man who may not want to be gay and will think sleeping with women will halt suspicion and allow himself to think sleeping with women will change him.
In Lawrence's case, it could be done to many things. He may not feel sexually attracted to Bernice and wants to marry her for companionship. Or he may be nervous about having sex with another women since his wife. Or the abuse and treatment he suffered during his imprisonment just left his scarred on what's right and what isn't when it comes to sex with anyone.
