My opinion is that it should hurt too badly. Of course one way would be to use maybe some coconut oil / butter, that's more organic that petroleum jelly.
I think if you use the jelly or other means for "slickness", then a rinse and a wipe after use should be OK. Maybe after few sessions or once a week, depending on your schedule, you could scrub it a bit harder.
I don't find so much difference with the [words=https://officialhydromaxpump.com/?uid=6&oid=2&affid=98]gaiters[/words], so if you have several, you can keep switching, especially if you use the Vacu-vin mod.
I definitely vouch for the Vacu-vin modification with the [words=https://officialhydromaxpump.com/?uid=6&oid=2&affid=98]Penomet[/words].
If you received that cleaning liquid with your purchase, be sure to use it from time to time.
Excess build up of oil or petroleum jelly can also affect your skin, so surely do the wiping at least after a session.
[words=https://officialhydromaxpump.com/?uid=6&oid=2&affid=98]Penomet[/words] section is truly quiet, mostly due to bad customer service and faulty products shipped, at least from what I've read.
No e-mails received, despite I bought the Premium
package a long time ago. Maybe I could try contacting the support, but it seems like a big fight, at least according to several members who've done it.
