Hey, if you think he's cute and would like to get to know him better, why not, if he turns you down, you can always ask the other guy as a back up.
I say go for it.
Hell yes. Get all prettied up and go for it. As long as a guy doesn't already have a date and you don't come off weird, AND you look good you'll get yourself a date.
You can ask me if you want, but I can't dance at all because of these huge tracks.
YES. If you need to be nervous about it, be nervous, but please do challenge your fears whenever they pop up so you can heal them as soon as possible and go on to live the happiest life you can!
