My problem with these tags is that most of the time its HUGE tits and HUGE asses. Its like no one likes normal boobs anymore, its either flat chest or enormous sack
Most of the time I am fine with all sizes. but you are right, in some cases the combination of age+size does not really make sense (even as a massive genetic outlier).
if a girl has a big ass but a flat chest the fat ass would make it up for me but if she had big tits and a flat ass I'd be disappointed that is to say I enjoy both tits and ass but a lack of ass in a girl would lead me to finding her less attractive more so then a lack of tits
