There are social behavior differences. One on one you may be great together but will you survive outside the bedroom so to speak.
I have dated up and down the age scale. The younger women's social environments involved the beach, hard bodies and a night life that was hard to maintain at any age. 'What we had in common.'
Conversation however, was very limited and shallow. Once you hear their brief story whats left to talk about?
Without enough in common any relationship will fail eventually.
Life age does matter but it does not have to stop you.
What makes you alike not different?
