Hell yeah, especially if hes hot!! If your a bit wary about meeting up with this guy then double date or go somewhere public with loads of people round.
Meeting on the street isn't really any different than meeting in the grocery store or church or somewhere else "safe." Just go to a public place, take your cell phone, and make sure someone knows where you are and when you should be home (just check in with that person if things are going well and you stay out later so she/he doesn't send out a search party :) )
Why not?! What difference does it make if you met him on the street, in a pub, or fell over him? End of the day you met him, and he wants to go out with you. Like above says, if you are wary on this fella, go to a public place, a pub you may regularly use, if need be, ask some of your friends to be there dont necessarily with you on your date, but say in the same pub so they can keep an eye on you from another table, if not this solution. Give you number to a trusted friend, tell them where and when, and text them everytime you change pubs/clubs, so if anything goes wrong they know roughly where you are. Have fun, dont worry, dont go anywhere you dont want to, like his flat.
