Not necessarily.
I'm 32 & feel more attractive to others now than pretty much ever, largely in part because I'm physically fitter than I've ever been.
Also, sometimes age is relative to others' attraction criteria that are entirely beyond your control. i.e. I'm only attracted to guys younger than myself, so older is a turnoff. And for a friend of mine, he's only attracted to guys that are at least 40, so anyone younger is a turnoff. At 25 you may be more attractive to some and less attractive to others, same with 30, 40, and so on.
People don't have an expiry date and there are no set rules for what age is more or less attractive to others. It varies for everyone.
