Help me, I fall in love with every woman?

Try and abstain from women for a while. Let's say for a couple of weeks. See how it goes. And while abstaining, sit and think which one of ALL this women you like you're in love with the most. Then go for that one. It's understandable due to your age. But a bit of reflecting never killed anyone. So take a deep breath and take a break. I'm sure after these two weeks you'll feel much more wise and just chose only 1 woman. But don't take my word for it, that's just a suggestion!
