I am new and just starting to cold approach women. I don't have a problem running an opener and can generally open most sets I approach. I tend to get nervous and fumble a little, but I assume that goes away with practice. My problem is after I run an opener, how to continue forward. Today I ran a cologne opener where I had sets both mixed and regular smell my wrists. I found that afterwards I didn't know what to say. I asked a few how everyone knew each other, but got nervous/flustered and went blank. I go out alone because all of my guy friends are in relationships. Is having a wing important or is going solo fine?

Thanks in advance
