Find the girl ( TGirl ) that is the biggest turn on to you, and one day call her into the room and show her. Just say look what I found. Make sure at some point she realizes that you are turned on. ( an erection at this point would be good ) Dont make a big deal out of it the first time. Then later show her another and make sure she sees you are turned on. Then one day tell her about a Dream you had and describe the dream. See how she reacts.
