Yea, definitely looks like a male. I would still give it a few more days just in case. You're not at risk of pollinating your other plants yet. If it's a male, put a large bag over it, pull it away from your grow area, and cut off at the main stem, killing it.
If you want seeds, you can keep it and let it pollinate, but most growers don't go this route because your harvest will be ruined.
