No way the OP gets matched 15-30% of the time! That's an insane rate. I match probably around 1 out of 20 or 30. I ain't the best looking guy around but I ain't the worst either.
A 25% rate of the girl sending the first message is also outrageous and must be a lie, unless it is including the fact that probably 3 or 4 out of those 5 girls were fake accounts. Fake accounts are truly the most annoying thing about Tinder. Girls just about never send the first message, I'd say at most 5% of my non-fake matches will send the first message.
If the OP is being real then that dude must be damn good looking. Also it could be that maybe Tinder shows new users higher up so they get more swipes to get them hooked, who knows.
To the person who mentioned Bumble, Tinder has lots of hot girls but Bumble hot girl percentage is insane, definitely the best app for checking out lots of hot girls. The thing is though, that girls are so disinclined to send the first message that even though the whole app is built around the fact that they MUST send the first message, they hardly ever do! Makes the app pretty awful except just to look at pictures of hot girls.
