I have sorta limited relationship experience but I've never had a partner that was open and free about sexuality. That's one thing I've really hoped to find. Approaching sex as an exploration and diving into new things makes it more enjoyable.
Instead of "eww gross" they would be like "VR porn? Awesome let me try it!". Owning your sexuality however it goes should be a meaningful part of your life. There are too many people that get worried about what others think or uneasy because they were raised with weird self-body images.
I vote for porn in a healthy relationship. If you can find someone that trusts you, then they should be cool trying things out for themselves and getting into it a little. There's nothing shameful about it. It's fun.
My last girlfriend guilt tripped about kissing in public. If she would have seen SLR in a headset, her head would have exploded. It's not worth it. Be with people that get you.
