Sometimes really personal sex questions, because I feel like it’s too intrusive.
I also usually try to avoid, like the plague, any religion question and I am happy that there’s somewhat of a moratorium on certain types of religious questions. They seemed like an invitation to argue and I am not into arguing if I can avoid it, but nor am I into being “jumped on” or criticized for something that a website is not going to change my mind about.
I always keep in mind that even though I am anonymous on Fluther, there’s always the chance that one day, someone I work with or work for or someone in my “real” life might figure out who I am, and I would not want them going through my questions and answers and really learning about thoughts, opinions, criticisms, etc. that I don’t necessarily want out there. I am pretty open on Fluther, but there are some things I just hesitate about. I also try to avoid putting in certain details in my answers that might make it easy for someone to figure out who I am.
