I would heartily recommend spinning, it holds no real fears if you start at a decent height, and once you have done a few your confidence will increase.
The C152 is ideal, because it is hard to get it to spin in the first place. If you put in half a turn of nose up trim before you start the manoeuvre you can take your hands off if it all goes wrong and it will recover into a dive just below Vne and start to climb (provided you close the throttle!).
