Here's another pic bro, you see any dough?
Obviously looks are subjective and variable depending on where you live and compare to others in your environment. In the midwest, you'd be considered in shape an fit as majority of older guys get to be obese or out of shape.
Personally, I think you are skinny and fit(good thing) but not muscular or jacked. Girls aren't going to notice your muscle tone underneath clothes and by the time any girls get to see it, they already like you enough to sleep with you. Unless you are at the beach, just being on the thin side and wearing good clothes and having a good face will attract most girls.
Now guys from California/Miami/etc. and such have a different environment where there are many more healthy and fit people living there. So their reference point might be skewed and you could actually be "doughy" to them.
But this begs the question on whether your girl see's you as "doughy" too because if that's the case, she will not have incentive to improve herself or lose any sense of security when you are out and about and if other girls check you out.
Ultimately, we are talking about her and whether you'd be comfortable in the long run to stay with her if she let herself go or refused to improve her looks. Has she ever said anything to you about improving yourself in any way? (clothes, hair, hygiene, appearance)
