<human>: My girlfriend and I have been together for years and our relationship has been wonderful, I adore her. I'm just worried and I know a lot of this is an issue with myself.

She has an amazing body, which is obviously going to attract attention from guys. She has small boobs so there are many days she does not wear a bra and she also has nipple piercings, which show through her shirt. When I'm with her I see guys completely stare at them and get really flirty with her. I've brought it up to her and she is completely oblivious to it and insists that she would notice if that happened.

Obviously I don't want to be a weird controlling boyfriend and tell her she can't dress a certain way and I try to not be jealous, but I'm just worried. Growing up talking to guys I know there are really messed up people and I'm worried about what could happen to her, especially because she doesn't recognize when guys are flirting with her or looking at her weirdly. 

I know it's not her responsibility, but I just don't trust other people. I don't want anything to happen to her. I feel like I have no options. Should I try to express my concerns without it seeming like I'm blaming her for anything or is there a way I can just get over this?

Summarize the given text in a few sentences.
<bot>: My girlfriend dresses in a way that attracts a lot of creepy guys and I'm worried about her, don't know what to do
