be carefull the male ploen is potant shit basicly every little bud you get with liveing pistles comming out dusted with polen will form seeds. if theres a fan shit can blow around you can baggy a bud (baggy pre filled pollen), ither way your just gotta be carefull as to not get that shit everywhere.
best way is have you polanated plant in another grow room if possable and not be touching back and forth .... This does not make Fem seed this is just to make a hermaphdite plant and produce normal seeds.
