Hello, and welcome to the forums!
Sorry to hear your wife is being a bit weirded out by this. But things are what they are, aren't they? If you have ED, or at least, inability to orgasm in a more traditional fashion, and nothing can be done about it, then it is what it is, and this brings pleasure to you.
Prostate orgasms can be awesome! But then, I'm bisexual (male) and well, I discovered I liked that sort of thing as a teenager. If whatever I could get my hands on fit, I'd sit.

I know there's a stigma associated with it, and I can easily see a woman thinking it's 'gay'.
Is it unnatural? It's nerves, and pleasurable sensations. Is orgasm unnatural in the first place? Lord, you wouldn't be the first straight guy who liked a finger up the backside. I've heard of women doing that for their guys during fellatio. The prostate can be fun.
Is it detrimental? Getting used to having prostate orgasms might spoil you for trying the usual methods, but you already have problems with that. What works is what works. Are you being too rough with yourself? Then I don't see it being detrimental, unless she's holding out for some miracle cure of your orgasm issues.
An evolution of your sexuality... only you can answer that. You're not the first man to find out 'hey that's enjoyable!' quite apart from sexual orientation. Unless you find your sexual turn-ons to be changing, I don't see it as anything but discovering something that feels darn good. Of course, there's Pegging. But still that's between a girl and a guy.
Be nice if she gave a hand, not to make a pun about it- and helped you to enjoy it, instead of getting soggy and hard to light over it. My sympathies.
Do y'all still engage in other sexual play? Or do you think she's feeling left out?
