It’s not bad at all. It’s normal. Most guys never talk to their crushes at all. They just sit there and pine over them and never do anything because they don’t want to be rejected.
When you’re ready for more, pick the one you like the most and ask her out. If she turns you down, wait for a week for the sting to wear off and ask the next one out. If they all turn you down, develop some new crushes.
