Showing interest

A question:

Guys: How do you personally show a girl that you are into them?
Girls: How do you know when a guy is into you?

I seem to be suffering from a particular symptom of NGS. I am embarrassed about making comments about my own sexuality in front of women. I focus on making them "like" me. However, I'm not spending enough time giving them hints.

I'm just the funny/confident guy. My flirting is subtle and I think I need to take more risks.

Any tips?

Welcome to my boat :/

Well it can become obvious if you talk to her clearly a lot more than you would talk to any other girl for starters. Asking her out on a date etc etc. there is many ways you can do it, just be creative
