Does an age gap relationship make sense?

It depends more on the ages and stage in life. At 20 I would have had little in common with a 35 year old, but at 40 I am quite compatible with a 55 year old.

my friend is 33 and his girlfriend is 18 going on 19. they get along really well.

I think for me I'd want it kept within 10 years. Much more than that in either direction and there will be differences arising from age even if you're not seeing them right away. There's a lot of experience to be had in a decade's worth of life that I think at times would make it hard to continually relate to someone that much younger or older. But there are of course cases and people where this wouldn't even be apparent. We're a fickle species.

It depends on the agenda. It can work as a simple arrangement, certainly with a 20-year difference but there needs to be much more circumspection if children are to be a possible outcome. I don't think it is good for children to have a parent who is of grandparent age.

It has been problematic in my experience. Much over 10 years, I would say to avoid.

5 yrs below 28 and 8-10 as you get older

×/- 10 is safe for societal norms and minimizing ahead gap related conflicts. I've pushed the limits both directions and it can be done if the bond is strong enough. Lots of stories out there. But yeah rule of thumb no more than ten is the easy road.

Yeah 10 yrs give or take

3 months. No exceptions!

Well I've dated men who are way older. Never saw a problem.

I dated a woman half my age last night. I think once the younger partner is in the 20s, it's all good.

My Tennessean wife doesn't care about our age difference

As long as its legal.
