Yeah pretty much what i thinked i think this guy is the tipical friend that is very pushy to his female friends and the girls make that excuse to make him leave them alone i can think that one your female friends can be lesbian ,but everyone, thats very rare. In my group of friends the only person thst is gay is a guy that swings both sides but my female friends are all straight.So every girl you ever met turns out to be gay? Interesting.
Has it ever occured to you that it might be your fault? You either turn them gay or they lied to you so you would leave them alone.
