Thank you, Eileen, because I was thinking similar thoughts as you and have held back on commenting because I was too furious to think straight. The following is a very calm version of my initial reaction to reading Tammie's post.
I am a regular/charter member at one of the local Gold's Gyms and I have been a member of other exercise/sports venues. If I ever happen to see a MTF CD/TG in the women's area, or dressed in a swimsuit as Tammie suggests, I will immediately notify the management to have that person escorted out of the area if not out of the gym entirely.
There is a proper place for CDing, and a women's-only gym - - or the women's area of a co-ed gym, the pool/sauna/hot tub, and/or the locker room area - - is
NOT it.

For Tammie to do so implies a narcissistic personality with absolutely no sense of decorum, of right-or-wrong, and your GF is just as guilty.
I have absolutely no problem being with CDs or TGs . . . but the women's area of a gym, or in Tammie's case a women's-only gym (Curves), is violating a sacrosanct area that is restricted to
women only, and 'wannabes' have absolutely no right to be there.
Now if Tammie, or anyone else, has had MTF SRS (or is well along in that process, ie had an orchidectomy) then that is a different story.
Sorry, Tammie, but the proposed actions by you and your GF exceed the bounds of decency, and you do
not have the right to subject others to your role playing, for that is all it is, role play.
