what he said^

i had the same problem, i used a small pair of nail/manicure scissors, small is better, you only want to cut off the male bits, not mutilate the plant, haidressing scissors sound ok.

expect a little bit of seeding in the final product, but it will be minimal, and youll still have a happy ending

if you only got one plant, dont chop off the side shoots, just tackle the male flowers individually....unless the side shoot has a high male to female ratio,
youve found the problem, now its all about damage limitation
