DIY mushroom pumping??
I was browsing some Glans expansion pumping cylinders on the market and the LA Pump model seemed reproducible to me with a regular cylinder and a tight sleeve. Basically my question is, If I put on a tight sleeve over my whole shaft with just my glans exposed for a pumping session, will it be putting all or most of the expansion on my glans? Is this a good way to target growth to my glans?
