well, when i was 18 i dated a 23 year old... and thats as bad as im about to go. my last boyfriend was my age and i prefer it that way.
I'd only date someone my age.
I'd allow someone to be 1 year older, MAX!
2-3 Years is fine by me but no more.
I'd allow 4-5 years but thats it.
5-7 years, just like you Devil Man!
7-9 years, but that's pushing it.
10+ years because I'm not very fussy
20+ years. I'll date anything you put in front of me
40+ years. I am a filthy pervert
