When sexting with a gay man, it's important to make sure that both of you are comfortable and that no boundaries are crossed. To keep the conversation going, the key is to find creative ways to express yourself without being overly explicit. You can start by describing your physical attraction for him in an exciting way - compliment his eyes, or describe how you feel when he touches you in a certain way. From there, you can move into more suggestive territory and talk about fantasies or experiences that turn you on.
