<human>: My girlfriend has always been overweight which doesn't bug me in general. The thing that bugs me is that proportionately her arms seem to hold a lot more weight than the rest of her. 

Now, I need to get some things out of the way here: Since I can remember being interested in smooching ladies arm fat has always been probably the biggest physical turn-off for me on anyone. I am 100% aware that this is **my** issue with perception/ preferences and that physical appearance isn't the most important thing ever.

I'm overweight myself so I feel that it's hypocritical on top of inappropriate to bring this up. The problem is that its becoming warmer around here and she is wearing looser/ more revealing clothing (as she should) and I'm finding myself not sexually attracted to her when her arms are showing. 

This ends up leading into a cycle of me wanting to say something then stopping myself. I then remind myself that this is me being a shallow-shitty person which makes my slightly upset. That then ends up being the mood I'm in which is not fair to her at all. I feel like I owe her an explanation as to why I'm acting weird but I don't want to make her feel like it's on her to fix this or that she feels the need to cover up.

Summarize the given text in a few sentences.
<bot>: I really enjoy being with my girlfriend but the weight on specifically on her arms has been bothering me recently and I don't know what I should do.
