For best results, Bathmate should be used 3-7 times a week for 15-20 minutes. The vacuum pump is easy to use – it is filled with water, excess bubbles are removed, and it is placed on the penis.
It is then pressed against the root of the penis several times to squeeze out excess water and create a vacuum. With regular use of the Bathmate vacuum pump, blood containing a high proportion of oxygen flows into the penis.
The purely male toy relies on special “water” vacuum pumps – these use water pressure instead of the vacuum created by sucking air. Bathmate pumps (Hercules, Hydromax, Goliath and others) are mainly used in the shower.
Because of how heavy they are (due to being fully filled with water), it is advisable to buy shoulder straps for them. On the side of these men’s aids is a scale on which you can check the effect of the vacuum on the size and strength of your erection.
The problem here, however, is that water is known to optically curve, so the results measured on the pump are not accurate. Still, these medical/sex aids are among the very preferred among competing types – despite the multiply higher price.
