I just realised this recently, because I got close to a girl who was chill, in the same career field, very mature, and very very cute. We were only talking on social media but we hit it off so well, until I realised she is 4 years elder than me. All attraction just vanished. There are also a few girls in my social circle, who are interested in me but I'd never date, because they're too fat , older than me or were just to promiscuous before. These things have made me realize that any kinds of preference is fine in dating.
