Congrats!
When I got married, nearly 2 years ago, I remember startting a thread called "I finally joined the ranks of the 'respectable' ". Looks like you are too :)
If you're skills with the blade aren't yet up to par I'd suggest going for a barber shave, with one condition: once you find a barber who still does SR shaves give it a go first BEFORE the wedding. Some barbers lack the skill required to avoid nicks and irritation, so it would be best to experience it before the big day. You may luck out and find a pro....
Best of luck,
Ryan
