Honestly, I think the whole MTFTM thing proves one thing: people should be able to do what they want to begin with, and no one would have regrets. That being said, even regrets sometimes can be a positive experience, as obviously that guy made a lot of money being a woman and learned from the experience. I mean, it's not healthy to play around with your body like it's play-doh (I know that from two botched rhinoplasty procedures), but at the end of the day, you only live once - if you absolutely know you need to change, and only undergo the change with the most professional doctors around. Things are now possible in this world that never have been achievable across the face of the planet. The MTFTM guy on the last page? If he didn't transition to female when he did, he may have committed suicide like literally millions of men across the planet's history. However, he was allowed to at least transition in some sort of way, he's now proud he has a vagina, and he seems to enjoy transitioning back into a man. What's there really to hate on?
I'm sort of the opposite myself, I'd love to have a feminine face, and as long as no one saw my penis nor cared that I had it, I probably wouldn't have a huge deal if I never underwent SRS. The honest truth is I'd never dream of using my penis in a sexual scenario, but until I achieve a feminine face, I would actually feel horrible with a vagina (I'd feel like even more a monster, looking like a man but having a surgery-made vagina - I need entirely pass a girl first.) so I'm only looking as far into the future as my emotions allow. SRS is something for me that'll happen when every other step in my transition is entirely comfortable and happy, and because no man that I socialize with wants to stick his penis in the vagina of a man who looks haggard, I'm not to worried about it until I become pretty. And even then, it's no rush, I'm never going to push myself into something I merely guess on, it's either going to 100% be my heart's desire or I won't do it. Being pretty and "female" face-value is something that I've dreamed of all my life, looking natural in pretty female clothes, being an actress, being a romantic, cute partner.....but having a female genitalia that a couple people on earth will ever see? It's never been a huge deal to me, I've never had a bad situation arise because of my genitalia. So I'm beating what's actually caused my dysphoria first, and seeing what happens after that.
