IT depends on what you want. If you want some seeds, then segregate him collect his pollen and selectively pollinate some buds for seeds, using a cotton swab or something. If you want alot of seed just leave him in there and put some plastic underneath, they make quite a mess! If you dont want any seeds then just kill the bastard, bag him up and throw him away, and take cuttings off of the female you wish to keep.
