Despite your asymmetry and nose (mostly just the smaller nostril), you are actually good looking. So, that's a feat in itself. I think it's because you have excellent features otherwise (hair, skin, lips). These matter. Now, whether jaw surgery is worth it? Eh. In general fixing that kind of asymmetry is not going to work out. It might, but I'd put the odds on it not working out correctly, and then you'd be left with some other face, al the potential risks, and probably a worsening of your nose.
I personally don't find any of your issues offensive. Do they stray from standards? Yes. Is it offensive to look at? No.
I'm about as far from gay as a man can be, and I think you look (a little wonky) but attractive objectively.
