Most Helpful Guy
I'm quite similar to this guy, I do expect girls to look good and I won't date them if they'll look bad, but I make sure I'm always well-groomed, I work out regularly and I dress good, otherwise it would be hypocritical to hold such views!
From my position, I would expect you to eat healthy, work out and take a decent care of your hair and face. I don't expect girls to dress-up top-notch every day like to some kind of a fancy meeting like a wedding for example!
Plastic surgery is any useful only for permanent flaws in the face, like nose or something, so if he already haven't even mentioned anything like that don't worry it's highly unlikely he'll ask you to go under the knife!
And the truth is that plastic surgeries are okay only for very serious flaws, so if you put some make-up and get a good haircut and look great, you don't need a plastic surgery!
Most of guys actually automatically don't even notice mini-flaws to girls, and if more the guy is into the girl, then more he'll not notice such things, it's natural!
And getting old doesn't mean doomed looks, of course the count good looking people severely reduces after 40, but even past it it's perfectly possible to remain good-looking!
And you're still just dating him, don't overanalyze too much and about too distant future!
The chances are he might suck at some other department, not this one! ...just joking!
