A creative industry professional whose work I’m a fan of keeps making inappropriate comments during creative conversation.

The title explains most of it. When I try to engage in conversation about art and whatnot, it’s met with a joke about “adult sex toys” or talking about someone he hooked up with. I’ve also discovered he follows NSFW accounts on his professional instagram which makes me all the more wary. What do I do about this? I admire his art style and craft, and I’m a fan of it. But he really creeps me out. I’m for sure not messaging him first anymore, but at what point should I block him? He’s a strong connection and it seems to me that he’s well aware of that.
