you could, but I think it is difficult to do. It would be difficult to divvy up the time in which you would spend with each. And for the most part I believe people who tend to have a large group of friends with many members of the opposite sex that they hang out with tend not to date a whole lot.

While people who do date alot tend to not have a large group of friends but just a few good friends. (and not many other friends of the opposite sex that they hang out with).

It would be very difficult to divvy up the time for each.
