Hi Aniya,
For me HRT was an absolute blessing. The Depression that undiagnosed GID had caused me to suffer ceased within a few days, and I found a whole new level of emotional sensitivity I never knew I had. I am now well on the way to a body that is congruent broadly with what my mind says should be there, and I just basically love being a girl.
Regarding sexual disfunction, after a short term thing with a non-op transgirl, I found to my pleasant surprise that we both performed completely satisfactorily on a number of occassions. Actually, although I would rather be without mine, if I was forced to be non-op I would just get a prescription for Cialis and go for it! Therre is a lot more to sex than penetration though, in fact I have found a number that are actually a lot more fun, and they don't end quickly either.
Karen.
