I think that as long as the person is of age(21, so there isn’t any limit on the things you can do).
Hopefully that person is good enough to have a mature relationship, because that is what Vernon J is looking for.
In theory I wouldn’t date anyone younger than 23, but you never know.
I don’t really care about the ages. I think it’s because my parents have a 20 year difference (my dad is 71, my mom is 51). Growing up with it I didn’t know it was “weird” until my friends with parents closer in age told me it was “weird”. I think if it works, it works and who am I to judge?
