Def a male, you can see plain as day the pollen sacks. Yank them out and and get them completely away from any females unless you want a shitload of seed. As for getting 3 out of 3 to be males (which sucks) but sometimes thats the way the cookie crumbles. your best bet is to plant at lest 10-20 seeds to insure you get females or you can always buy fem beans.
