I want a younger guy to play with
You no longer into older men?
Yes, not interested in older men anymore, they are boring me to tears. I think I can make the younger one mine if I feel sure he likes me.
Just wanting to replace your old boyfriend with a younger guy means you are bored to you. Taking into consideration your choices, it is pretty much bad news to just dump an older person for a younger one.  Stay together with your older guy for the sake of the family, they will never understand your moves because you are a female.
I don't need a family, I'm single like a tennis ball. Older or not, they all feel the same when they enter you.
You can date who you want, but I'd suggest you don't let the shallowness of age dictate your dating options too much. As long as the guy is of proper age, you should be looking at their personality, not age, to determine if they are worth dating.
