I believe that full spinning is not compulsary on the JAA PPL. At the school I work at we demonstrate a full spin or two after the lead in lessons of slow flight-stalling 1-stalling 2 if the student wishes to see it. Perhaps a more important thing to demonstrate and then have student practice is recovery from incipient spin which is a much more likely scenario. This does not have to be entered from the most terrifying angle and aggressively when your student least expects it. Perhaps getting a good heads up on incipient entry/recoveries and increasing your handling confidence in the process may well help you over this difficulty. The first time I ever did spinning was on my FI course and it was performed with vigour which at best was exhilarating and at worst down right scary and sickly. At points I really did wonder how I would ever cope with it, but now I really look forward to it and it seems that even a 152 can bite a bit sometimes so sensible heights and airmanship is called for.
