Yeah, definitely. 17 is out of the question, I'm not @Adonis ffs
To be honest, 19/20 is not usually the way I roll either, which is why I came on here asking for advice the other day.
The primary reason the age difference is troubling me a little bit is not so much the actual age difference in years, but more a fear of becoming too attached to someone who is likely to not want to settle down for quite some time.
