thanks for all the input guys, I took the plunge on Saturday and shaved the lot off.
reactions from most male friends was that I am no longer a man, which was to be expected from my lot tbh.
still not a fan of my chin, but the reaction from female friends has generally been good, and most people (socially and several at work) said I look a lot (5-10 years!) younger, so I might try this look out for a little longer and see how well I can settle into it. failing that I might try Jaz's suggestion of a full beard, and keep it fairly short.
will get another pic up soon so you can see (if anyone cares!), and again, thanks for all the input, both positive and negative
