I used a message board for some sexual roleplay recently. I'm not proud of it, but there it is. I ended up quitting after a couple of posts back and forth simply because, although my partner said she was 18 (as am I), I began to wonder if she was actually underage, ergo I'm a sexual predator, ergo I'm a rapist corroding someone's sexual, emotional being etc. I explained to her in a message that I couldn't continue because of my anxiety, and she hasn't responded to the message or been on the site in a few days, which is making me feel like she may have committed suicide. Yippee. I know more about OCD than I did last time I went through something like this, so I'm not "feeding the beast" by compulsively seeking reassurance, but living with uncertainty is obviously a challenge unto itself.
On a positive note, haven't had many intrusive violent thoughts lately- I think taking Buspar might have something to do with that.
