considering that I pay 150 per session with mine, no i dont think its too expensive lol.
Also, who says girls don't shoot guns and flirt with girls? ->-bleeped-<-, I ride ATV's, go jetskiing, love video games and curse like a sailor, flirt with boys AND girls. Transition will turn you into the woman you feel you are, it doesn't mean you have to leave your hobbies behind. There is no right or wrong way to be a man or a woman.
To answer your original question though ~ no, these thoughts don't stop... you can bury them, forget about them temporarily, or ignore them, but they're there and will eventually torment you; the only way to ease thoughts of transitioning, is to transition 😛 E is a hell of a drug, I too was scared and unsure and was "happy" being a guy, but after realizing that i had lived 20+ years of my life being known for my anger, my hatred for everything, my low self-esteem, never feeling attractive, and severe suicidal depression, I realized that I was kidding myself. 6 months later I'm riding the E-Train and its a smooth ride xD
