Honestly anything under 20 (18-19) is young for me, but on the rare occasion if I can find a uni chick I don’t mind. Currently seeing a girl and she’s 19.
I would like to believe during punts I am regularly looking or seeking girls who are in their 20s and as high as mid 30s. So that is what I generally go for 20s, mid 30s if they’re hot. Now if you deceive me it’s a whole another story.
