I always feel that friendship is a good first step for more interesting relationships.
You cant date guys you never met - so meet guys in a non threateningnon sexual manner.
I'd say figure out the sort of guy you fancy and then join an organisation that caters to that "type". If you like jocks, join a sports club - if you like brainy guys join a chess club....
If you like geeky spotty teenagers, join a chatroom.
