Hah, I have to say that 2 out of my 3 bredli are really not very good handlers, the other is the second best snake I've ever owned
Saying that, I haven't had much time to handle them over the last couple years, but with the effort I have put in they've calmed down a lot. Most snakes will respond well to regular handlings, though there will be exceptions.
What I think you should be getting out of this thread, is look at the species suggested and decide which one appeals to you. I prefer a decent sized snake, so would be looking at coastals, diamonds, or bredli, and then I'd choose bredli because they're gorgeous
realise that It'll be a couple years before a snake gets to an 'intimidating' size, and by that time you will have grown up with it enough that it won't bother you.
If smaller pythons appeal, you can't go past childrens (anything antaresia).
For a first snake, just be sure you buy one that is eating well, as it's a hassle a first time keeper shouldn't have to deal with. Try and find a breeder who'll talk it over with you, once you decide on species.
Enjoy
