You ever ask a date why they swiped on your profile? It's a good question for 10-15 minutes in to the first conversation. It's always revealing - about you, about how you're perceived, and about how the other person perceives you and what matters to them.

Also - bug your desired-sex friends and family. Show them your profile. Focus-group it. This has been massively helpful for me.

At the end of the day: change stuff and see what happens.
