Don't rush to conclusions. He is a therapist and will be dealing with people with a variety of issues. Having certain kinds of correspondents does not make a therapist a 'perv' - but he could well be dealing with someone who is involved in the porn, etc. industry. The correspondent could be the one with issues, not necessarily your therapist. There are just so many possibilities -- most likely this is a mistake anyway. There is a tiny little chance that your T is indeed a 'perv', but why would that be true, and not the other thousands of possiiblities? And how long have you been with this T - did you ever suspect that he might be a 'perv'? I honestly think this is more about you than him, and I hope he will be able to reassure you when you bring it up. Another issue worth exploring is you noticing this and investigating the details (I would have automatically deleted something like this without much thouhgt) - I suspect some long standing trust issues cropping up in your relationship with him, and I wonder why that is. But then again, this is all just a speculation and I might be utterly wrong...
