This plant had a noticeable smell even before flower from a few metres away...The pic aint the best but I see what looks like balls....no pistils, flower it and if its REALLY stinky, with tight clusters keep that pollen!
Things to look for in males...
Tight flower clusters
any noticeable smell
fast, strong growth
and yes, once in a great while you can find a male that will produce some trics (definitely keep the pollen from these)
