Is it okay to date your brothers' best friend?

I'd be very careful because if people aren't mature enough it can turn nasty if it doesn't work out.

My older brother (23) went out with my friend (17) and he was more into her than she was into him. He would ring up and find out that she was at my house and come over. I had to lie and tell him she wasn't around or she'd leave if he showed up just so she could have some space. He'd be upset and I'd be torn between supporting the two.

14 days after the first day of your last period. You have 3 days to shag yourself silly and hope it works.

I'm currently dating a guy that is my friend's older brother. I am fine with it since I get to hang out with her and she is fine with it as far as I know. His family loves me and my family loves him. My situation for dating your friends sibling worked out and we are looking ahead in the future for the both of us. We have known each other for 3 years and started out as friends - the best way to get a relationship. I agree with the first answer also.
