Regarding myself, I did debate whether to do the intro at all. I've been plagued a little with direct messages on here, Discord, and Patreon that are kind of bad, but overall, I think it's been ok. I actually get more leering and things of that nature way way more in real life than on here, etc. I even lost one potential client once because the husband was so clearly creeping on me that his wife wouldn't use me, and it was clear why... (I didn't think it was my fault so I felt bad, but I understood her position to be honest and I can't believe he had that level of disrespect for her!)
However, I do think my intro helped land my biggest Patreon, and he's the only one that's really gotten to know me a little bit personally. But I checked him out carefully first before opening up a little on my end.
Otherwise, I'm pretty cautious in general as I do worry about rapey guys out there a little too much perhaps...I even did have to drop one larger Patron and ask him to stop contacting me as I felt he was getting a little too much for me in an uncomfortable way.
The only thing I will say about incest is that I have a specific definition for it. It's perhaps a narrower definition than others might have for the word.
