To answer the OP's question, the answer is yes. I have a selective few with whom I have tremendous relationship. We know each others' real names and even DOB's, and some have visited my place. I know where they attend school and what they study and they know where I work, my position and the degrees I have obtained,. Relationship is more amicable when we both have similar hobbies. We travel to ski in the Rockies and Laurentian, and to enjoy the dual massage in the spas. We even attend martial arts classes together and also slip in some practice after our regular sessions. Being polite, gentle, hygienic and respectful go a long way.
