Male orgasm = pistol shot. Female orgasm = earthquake. Sometimes you can combine the two, which makes us MTFs unique, eh? I'm less and less interested in being turned on by visuals, too, fantasizing does the job all by itself. And my libido crashed after 5 months of HRT.
I'd have your levels checked within the first month - they started me on lowest dose and the estradiol gave me a ton of hot flashes. The spiro wasn't low enough to bring my T down to where it should have been, either; we increased it a couple of times, but as I said, it took 5 months for things to suddenly really become apparent, with my libido, mental state, and body development - the body development had gone on in a minor way all that time, at least. But I think girls who record immediate drastic changes are more receptive to low doses, or started out higher.
