Hi again. It was a massive relief to post yesterday after years and years of secrecy. Barelythere and bloblem, I can't thank you enough for your kind, supportive replies and advice. I've been doing alot of thinking about how I've ended up in such a mess. I'm not sure if this is worth posting but here are some recollections of events that may have influenced the development of my masochistic tendcies.
I have childhood memories of playing doctors and nurses with some other kids. I remember having to take my clothes off when I was the patient. Another similar game involved being a captive of some sort.
I had a surgical operation, long enough ago that I can't remember the reason for it but I've got a scar along the length of the underside of my penis. I remember this being quite painful at the time. I remember lying in bed afterwards, recovering, when for no apparent reason I had an orgasm. I'm not sure if the pain / pleasure aspect of this is significant. I also had about 3 other unrelated operations not that far apart.
I recall having a dream in which I was being manhandled into a rowing boat to be taken across a river. In the dream I was helplessly wrapped up in some kind of shroud. I don't know why but at this point I had an orgasm and woke up.
Later, I can can remember becoming aroused in class when the teacher described how Guy Fawkes was executed by being hung, drawn and quartered. Also at the school was also a book on methods of torture that I was very drawn to. Subsequently, I used to lie in bed fantacising about being tortured and executed. I guess the whole thing developed from there.
I can't believe I'm posting all this stuff

. Sorry it's a bit of an essay. Hopefully it'll do some good to tell someone about it.
Anyway, I now have big problems getting to know people in case they figure out I'm complete freak. Also, I still haven't told my friends and family that I'm gay (although they've probably guessed by now). All in all, I've got a quite a few issues. I think I need to get some help but not sure who I should see. I'm also very nervous about telling all this to another person face to face

. Any advice or experience regarding therapy / psychiatry would be much appreciated.
Many thanks once again to Barelythere, bloblem and this forum.
