Greenie, I think that your boyfriend needs to not take the handful of posts that seem like criticism, as representing the entire spectrum of CDers here.
It's true there might be more to talk about if a CDer wants feedback on makeup, hair, mannerisms, experiences with going out, etc because they do want to go out and blend, and so it may seem as if the bulk of CDers here present this way and go out. But overall, I think there are more CDers like your SO who just like to wear the clothes at home. We just don't hear from them as much since there is less to talk about? Or, maybe they are the members who talk about what color is on their nails, or what they are wearing today. There are also many pictures in the Gallery that are cropped at the neck.
I think that your SO should give this place a chance for maybe 6 months, so that he can get to know others who are like him. He might want to participate in threads to give his own viewpoint. I'm sure there'll be others who will post after him and agree. And if he wants to post in private, there is the GM section.
Last, I was like your SO in the beginning, it looked to me as if everyone here wanted to transition and sleep with men. But now I know that half those posts are pure fantasy, while the other half are just our more vocal members ... but most important, I wasn't paying attention to the tons of other posts that had nothing to do with wanting female body parts or wanting to sleep with men.
