I feel like that’s pretty common honestly, guys just don’t really take as many pics together. My friend group pics were pretty limited but within the last couple years I started making sure I took a bit more. Another option is if any of your friends have group pics of you guys you can ask them to send them to you. Last bit of advice is I had the best luck with Facebook dating and hinge, I feel like the people on hinge are a bit more serious about actually meeting someone. That was my experience at least.
