Most Helpful Girl
It really depends on the person and their lifestyle. They're all adults so at the end of the day, it's really an asserted decision on their journey, their business and nobody else's. Some 18 and 19 year olds end up going to college early or are forced to tackle adulthood by that time and actually may be able to relate and match levels with a guy who is 22 or 23. However, that won't happen very often in some parts of the world and it can become a complete unsatisfying disaster. For the guy depending on where he is in life, his maturity level, and the standards he wants in a relationship, he may feel like he's dating a kid. Just my 'pinion.
