Twinks are slim but soft, do cardio of you need to lose weight but don't build muscle, you need clear skin (preferably pale), somewhat tall is optimum but height isn't a massive factor, pouty lips are good and so are large eyes and long eyelashes, you need to look soft and feminine, being good-looking is important because men that go for twinks want them to be very pretty, but as always a decent face may have to be compromised on. Some gays go for twinks, but nowhere near most.
