What kind of stem rub sccent if any, is he putting off?
Do you know the genetics? If you've only got one plant to worry about you could collect pollen and use him for a future cross and to make seeds with, then you would make plenty of seeds and have extras.
Seeded bud can actually be more potent than non seeded buds, the trick is to not let the entire plant get pollinated, just a few pistils here and there in preflower, or by isolating one branch to add pollen to, then afterwards give the plant a light rinse to sterilize the excess pollen.
But yeah that's what I would do since no other plants are needing that space and your plant is close to dropping some good seed making pollen soon.
