Age Difference Between Partners/Couples

Purely for sex, anything over the age of consent, I suppose. for a relationship, roughly five years either way. much more than that, and I find it becomes harder to relate.

I am somewhat flexible so assuming this one rule (they are over 18). I am ok with +/- approx 5-6 years. I say that because honestly one more year wouldn't kill me. But after a certain point the difference in generation to me makes it harder to communicate.

5 younger when I reach 25 and 5 older

My last partner was 9 years older than me.

Age to me isn't a huge factor, but I will admit to having a thing for older men :P
