Working on your PC muscle can help too, and if you're not sure what that is, imagine trying to hold back peeing while you're peeing. Painful because your urine comes back into your bladder (which can be unhealthy and sometimes dangerous), but if you work that muscle on a regular basis (while not peeing) and tighten it when you cum, in my experience I find myself shooting more and shooting a lot farther. Feels great too :) Builds up a lot of tension into a giant orgasm. |
