I'm pretty sure most girls will get stretch marks on their boobs to varying degrees. I'm a 36 D so know what you mean! However, within a year your stretch marks will fade in colour and in no more than 2 years they will be a little lighter than your skin tone in colour, and not nearly as visible.
As for whether or not guys care, I really doubt it. I've never had a guy mention there being any stretch marks, though many have complimented them. I'm sure that for the most-part if a guy will get to see or touch your boobs, the last thing on their agenda will be to look for anything that could be 'wrong'. As long as you've got nipples, you should be fine. :P
