I have never regretted giving a guy my number or asking to meet for a drink. I prefer giving him my number first but if I sense there is definite interest, I will do both at the same time. I already wrote about it: https://medium.com/heart-affairs/i-gave-my-number-to-10-men-in-real-life-and-10-men-on-dating-apps-fab521d7a1a9

When I ask someone out, I am doing the choosing. And I don't chose arses.
