Your dating age range?

I’m 31 and dating on an app. I have 29 set as the youngest age, but the app still pushes through the profiles of people younger than that who’ve liked my profile. It made me curious what other women in their 30s’ norms are - will you date people 5-6 years younger than you or in their mid/late 20s? Casually? Seriously? Would love all perspectives. It gives me the ick but feels a little unfair, especially when I used to be a 25 year old dating 35-40 year olds, lol. I’m bi so analysis of any/all gender dynamics is welcome. And I apologize if this is asked a lot - I tried to search the sub for a similar question and couldn’t find one!
