In terms of looks (or hotness as you describe it); the fact that beauty fades is true for both genders. So I'm a little confused about what you are trying to say.
I think both sexes, for the most part, put too much value/emphasis on factors that, in the end, have absolutely no bearing on their actual ideal selection of a soulmate. It's a sad and tragic flaw of the human species.
Just be yourself dude. Girls in your age bracket will come around. Stay away from anything sketchy and any younger girls and just trust that when you're opere it won't matter. Girls will always like you but they may not be your exact age. There's nothing wrong with being 25 and dating a 20 year old or 32 year old.
I'm much older. In my thirties. But I will tell you, most girls my exact age are not into me. Girls 3-4 years younger or 5-6 years older seem to be the girls who go for me. It's strange. But my exact age. Nope. It's very strange.
