I've had alot of issues with the balls being pulled in and tried alot of stuff and finally i found a solution that worked for me.
The seal will probably not be 100% tight but since in sit in the tub with the base of the pump below the water line its not really an issue - just need to repump.
So my solution is using a wettex sponge cloth with two perpendicular lines cut in the middle forming a +. Just mind that the cloth will grow when wet so make the cuts a bit smaller than your girth.
The cloth will function both as a comfort protection for your groin area and help with your balls get sucked in. I use a [words=https://officialhydromaxpump.com/?uid=6&oid=2&affid=98]X40[/words] without the grey comfort insertion and have no problem with max preassure with the [words=https://officialhydromaxpump.com/?uid=6&oid=2&affid=98]gators[/words]. When i use the Vacu-Vin it becomes a bit more difficult to keep the balls out.
Vileda Professional - Wettex
Just did this yesterday so only tried it for one session but it was my best session so far. Ive been using the [words=https://officialhydromaxpump.com/?uid=6&oid=2&affid=98]
Bathmate[/words] for over a month and I've had alot of issues with getting good workouts. Started with the [words=https://officialhydromaxpump.com/?uid=6&oid=2&affid=98]X30[/words], bought the extra comfort rings, tried with CR, lubes, condom and finally realized that it was probably a bit to small for my girth. Got the [words=https://officialhydromaxpump.com/?uid=6&oid=2&affid=98]X40[/words] and only got good sessions when i inserted the whole
package but it kind of hurt and also restricted expansion at the base. Also got pinched by the grey comfort insert so i started bleeding. So I was really happy and surprised that the Wettex cloth worked so well - Costs 1 $ and takes 1 minute to prepare.
