I am pretty gender neutral when it comes to friends, I got both male and female friends and probely more females but I dont really care..
if you want a group of guy friends maybe you could join some kind of sport or activetys who mainly include males..,
I remember when I where younger I played alot of soccer, and it where alwas 0 or very few girls, so you easly became on of the guys on the team, it very pretty nice and I enjoyed the company, I also got invited to an all boy party, even thought I never play videogames, and stuff I enjoyed it.
or if your lazy I guess you could get video games sleep overs and stuff, playing conterstrike or something?
