Surprised at how quickly I've become turned on by bisexuality

For context, my wife and I (both 30, married 4 years) have fantasized about hotwifing for a few years, but recently agreed to be open to doing it irl. We started chatting with some guys on Reddit, and some of them were bisexual. The chats opened up something inside me that I wasn't expecting.

A few months ago, I would've described myself as completely straight. I'd never had any bisexual fantasies or tried any anal or prostate play. Fast forward to today, and I just jerked off with a plug in my ass and my wife's biggest dildo in my mouth, moaning and sucking it enthusiastically until I came in a couple minutes.

Anyone else have this lifestyle lead to a bisexual awakening?

(I have talked to my wife about this a little bit. She knows that I'd be open to contact with our bull if it turned her on, but I haven't told her how into it I've gotten. This is still super new for me, so I'm trying to figure out how I feel about it as well.)
