When I came out to my wife last year, one of the first books she read was Helen Boyd's "My Husband Betty," which I had read a few months earlier. One of the more catching and controversial (at least for us) assertions that she wrote about in her book was the concept that sometimes people can potentially "progress" from merely wanting to be a casual crossdresser all the way to taking hormones and seeking SRS. When I first started getting interested in crossdressing a few years ago and upon resuming it this past year, I had never assumed that there was any kind of "potential" for going from being an occasional crossdresser to wanting to permanently alter my physical appearance. The only books that I had available to read when I first started crossdressing were "Crossdressing With Dignity" and "My Husband Wears My Clothes," and from those books, I came to believe that you were either TG or TS or something in between but whatever you were was unlikely to change much, if any, in terms of how much you crossdress or pursue permanent physical changes (if any). "My Husband Betty" threw that concept into question for myself and I feel that it has caused my wife a lot of concern and it probably has made it a lot harder for her to feel comfortable/secure with my crossdressing because there does not seem to be any real way (other than with the passage of time) to ever fully assure her that I do not and will not ever develop the desire to seek SRS or any other permanent physical alterations. If there is a "potential" for me to "move along the continuum" as Helen Boyd, then how can I ever be sure, MYSELF? I have thought long and hard about this subject and I can't ever see myself desiring SRS now or ever. Although I like crossdressing (and probably would do it more if I could), I feel comfortable with how I am physically and enjoy crossdressing primarily because I enjoy the rebelliousness/naughtiness of wearing clothing intended for women and presenting myself as a woman. What does everybody else think about the "contiuum" concept proposed by Helen Boyd and does anybody have any personal examples that support/refute her ideas?
