Hope someone will indulge me on this:
When did you start knowing about ntr? When did you start to enjoy it? Was it love at first sight kind of situation?
This is a complex question because "ntr" that you refer to is way too broad. Given that F95 is looking to modernize their ntr tags definition of netori, netorare, and netorase, I can try to answer each.
I've never had a "moment" where I became converted; but I've always been into rape / blackmail tags on e-hentai, a popular manga website. I love tarnishing pristine women and with the recent Western social movement of female empowerment, it stokes my fetish even more. Particularly once I've read from this

that uses Google search data and shows that women are the major consumers of hardcore rape noncon porn on PornHub and Google searches.
In terms of netori, netorare,and netorase...I've never once cummed while imaging myself to be the cuck. I've never once put myself into the cuck's shoe. It's always from a 3rd person POV to see how completely messed up the situation is (how such a pretty girl with a pretty face can do such dirty, nasty things). Or how such a strong, warrior princess with impeccable manners, looks, and sense of justice can fall prey to evil bandits, scums of the Earth. Yum.
Netori, given my sadistic approach to porn, is natural. The woman has to be worthy for corruption.
Netorare, I mainly love watching beautiful things break. If the thing isn't beautiful, what's the point? If a mountain isn't tall, is it worth climbing?
Netorase, I don't really pay particular attention to these kind of games. They're almost ALWAYS unrealistic.
