Well that's the thing. Men hit on me all the time and like 99% of the time I know it's because of my boobs.
It's hard to pick out the genuine ones.
I cannot possibly know what it is like to be in your position, although I can try to imagine, so whatever advice I can give has limited worth.
Anyway, no, your boobs are not TOO big. For my taste, at least, I wouldn't pass the chance to play with them. Of course, some guys will find the too big, others will probably categorize it as fetish, but that's just a matter of taste, and I'm sure your breast size would please quite a generous amount of men.
So, the most important thing is that you accept yourself and that you love what your genes offered you.
Now, if you want to know how to pick up the genuine guys, that can be a bit more complicated.
However, if you're looking for a steady, serious, commited relationship, my suggestion would be to take things slowly and see what kind of "chemistry" the 2 of you get from it. I'm sure that, if you first become friends with a guy and the two of you hang out for a while, you'll be able to tell how you get along with each other, how much you have in common, how he behaves next to you whether your showing cleavage or not, how much you can laugh with/at each other, how much time you can go on talking about everything and anything without getting bored with each other, etc.
I believe that will help you determine if that guy only wants you for your boobs, or if he really is into who you truly are.
I hope this helped. :smile:
