I know(I didn't then) an 18-19 year old(she's 22-23 now) that had been crushing on me . She was a lot more mature than the females in my peer group that was clubbing every weekend and collecting bodies/babies. She worked and went to school, rarely drinks and didn't smoke(and was fine on top of that) but the age difference and the fact that she had been crushing on me before she was legally able to date me
threw me off.
Point is the point at which people reach maturity is different for everyone(to a point). Some people, male & females, never reach it. I, personally, don't see anything wrong with it, PROVIDED that you go into the situation(and leave it) with everyone involved on the same page. If it's a fling and she's cool with it.... Fine.. She's legal. If the relationship is a bridge towards marriage.... That's cool too.
I'm pretty sure there will be all kinds of judgments but here is the reality... Single, mature, childless men want single mature childless women.... and the older women get, the less likely they'll be childless. There are more single females with children than single males with children.
Females, don't take it personal.......
