I don't know whether I have ocd or not. But, two years back when I went to psychiatrist he said that I do have ocd and I didn't take any medications.
My query is today I was in temple.. and was writing something on a sheet.. while writing I thing my ocd was amplified where I open the sheet put a dot and close.. open , dot and close.. it happened for some 5 to 10 min as my thought was if I don't put a dot, something bad might happen. But, suddenly ejaculation happened.. whats wrong with me? I didn't think of sex for even 0.00001% also.. I was in temple but why did I ejaculate? Please do help me..

There are many reasons and it is not to say what your sub-conscience may have been thinking of. I would be much more worried about opening the paper and dots, with concern of something bad going to happen.

Sounds like you need to go back to doctor and follow up with treatments.
