Okay so I went out wth a friend last Saturday and her friend came, and he was really cool.
And I want to talk with him, but he doesn't have email or anything but a cell.
And I don't know how to ask my friend for his number.
Anyhelp please..

Ask him for it it's that easy if he's single he'll give it to you in a second

Just ask your friend clearly about their relationship. If the guy is simple friend of her then she will give you number. Be careful when you asking their realtionships...

When you guys are together alone and you feel the chemistry is there ask him if he has any plans next weekend... when he questions why?let him know you want to chill... being straight forward with somebody can show your strong, intelligent , and independent.. when he agrees to chill with you next week you ask him how are you going be able to reach him... and with that said that's when he will ask for your number

Create something u need help, and make sure he is capable to help, such as, computer problem, or mend things at home, blah blah blah, after he give u a hand, u can thank him for a dinner. Do some trick, just let things happen.
