I was over on Yahoo a few minutes ago, and noticed that they have an article "Dating 101: Can Romantic Partners Have Friends of the Opposite Sex?"
In my twisted little mind, I immediately converted this in to "Can Romantic Partners Have CD/TG Friends"... since such friends would, at least at times, be perceived as being of opposite gender.
The article gives a fair bit of common sense advice for the uncomplicated situation, advice that would also apply well in the more complicated situations.
Still, I will toss out this question, especially to those of you in hetro-gender relationships: have you, in practice, encountered difficulties because your partner felt that going out with other CD/TG folk was effectively (at least at their emotional level) the same as if you were going out with someone of the opposite gender? E.g., if you are a MTF CD and you are friends with another MTF CD, then in practice has there been difficulty with your partner feeling as if you are "going out with a woman"? If so, then has the difficulty existed only if one of you is "presenting" as the other gender than the friend is, or has the difficulty existed only when you are both presenting as female, or has the difficulty existed even if you are both going out as guys?
In my own case, the relationship dynamics don't quite work like that. My wife encourages me to go to the monthly meetings, but isn't fond of my going out with anyone, no matter how I met them... and that situation existed years before I discovered I was a CD. But as far as I can tell, she isn't concerned about me "getting involved" with another CD/TG: she just finds the whole thing (and the people involved) somewhat weird, and a bit of a turn-off.
