Ya man, don't beat yourself up. I didn't know anyone with implants until my fiance just got some this December. I've loved big tits for years, and not thought I would luck out and end up with a girl with some (let's face it, there's a lot of competition for em). I'd known the girl for over a year, dated for over 3 and just casually brought up what she'd want for a nice wedding gift. Bam...she said "if money wasn't an object, I'd love to have my boobs done". Ya, I made that shit happen in 9 months.
It was awesome, I was able to talk her out of going for some 300cc hack job, went to Florida to a good surgeon and got 750/800cc on her first go. Sorry for the rambling answer, but you never know when you might get lucky and have that freaky girl you're with be down for something just like that too.
