Health: a few dates cannot instantly change 20 years of life experience! I’m not saying be matir issurim- just don’t add unnecessarily stringent regulations to further limit mixing. The formative years of ones life are the teen ones. If in those years one does not talk at all to girls one’s age, it can cause years of discomfort, anxiety, and social awkwardness.
Benignuman: a dating coach?? I don’t know from that. Most guys are just set up and expected to know what to do. They might get a word of advice from the mom before, but nothing serious or professional. That seems problematic to me.
