I personally love that he’d even consider it, I get that it’s near impossible because they’re establishing MJ in the MCU however there are ways they can establish him being Pansexual or Bisexual, followed by pulling a Gwen Stacy later down the track on MJ to remove her out of the equation. I mean, it’s not like one movie ago he was totally digging Liz before...you know...Michael Keaton happened.
I’d be down with it only if they could reasonably pull it off (or if they decide to insert Miles films and films later and make him Gay, though I would prefer Tom Holland’s Spider-Man)
