I think you look fantastic! Congratulations!! I've seen many women wear bikinis and they were not nearly as fit looking as you are so I say whenever you are comfortable GO ON GIRL!
I would love to reach the point where I would wear a bikini. Maybe of these days...HEY, how about wearing a sheer wrap thing as a tester - that might make you feel a bit more comfortable about wearing it out the first time - you'll be getting looks, but remember, its only because you look GREAT!
Way to go!!
