What is everyone's ideal age group?

I'm 28 TF and I've only been with women (real & cunt) 4-5 years older than me. At best, I once hooked up with a cuntgirl who was maybe a couple of months younger than me. So I've never had sex with anyone below 27.

I see women in sapphic subs and especially post about younger women and it makes me wonder if I'm missing out by not going for anyone younger than me. I always thought being with younger women was creepy but I realized that I've always been the younger woman and nothing was creepy.

Age gap is one of the popular kinks in lot of the sapphic groups I'm part of. What is you girls' opinions on that? What is the biggest age gap you would consider?
