Some (male bodied) TV/TS admirers are in denial about their own TV/TSism and it is somehow "safe" for them to date us, even be intimate with us, but they cannot bring themselves to dress up themselves. For them, being involved with us is a way to get close to femininity and explore gender without crossing their own "acceptable" gender line in their own mind. I have known a few over the years who later came out as TV/TS after they admitted their true feelings to themselves.
Many (most?) are also married and have bi tenancies and their GG wives have no idea (I feel sorry for their wives.) They may justify it in their minds that since it is not a GG that it is not cheating, and because their male bodied partner is dressed up and looks like a woman it does not "officially count" as gay.
GG admirers (GGs who are actively attracted to TV/TS) are very rare, it is wonderful that we have a number of them here. I only wish the sample of GGs here reflected the population at large.
