Needing Some Feedback

I’m 27, and I was having a conversation with my sister about our dating lives. Basically “How long should I date before I get married?” She’s been dating a wonderful man for about a year or so, and I simply replied “Two to four years, but that’s just me.” She questioned my reasoning because “A lot of women won’t wait that long because they wanna have kids.” To which I proclaimed my child free nature, as well as adding “if she really loves me, she’ll respect my boundaries.” She accepted that answer, but the reply has still bugged me this afternoon.

Ladies, would you stay with a man at least two years before marriage? So you two could really get to know each other before making a permanent commitment.
