Hey. Just a quick anatomy check here. A lot of women and other vulva havers have never actually gotten a mirror and image out and mapped their parts to their names. In some cases people have been mistaken, trying to push things inside their eurethra rather than their vagina. This can cause a lot of pain and does not generally result in sexual enjoyment.

Secondly, mechanically, this is supposed to be a fairly wet process. Dry fingers are really good for causing damage, but absolutely terrible for pleasure. They can cause abraisions in the soft tissue and even draw blood without any malice or significant force. Try using a lot, and I mean what feels like too much and then some, water based lubricant. I would recommend KY as a great starter as it is more jelly like than many others and lasts a bit longer.

Remember, if choosing between more lube and less more is always safer, more comfortable, and lower risk. It doesn’t reduce sensation, it increases it, so making sure everything is wet is important.

Water is not lubricant. Water removes all the gel features of lubricants and will dilute and wash away water based lubricants. Silicone lubricants are water resistant and can be used vaginally, but generally people find water based lubricants more comfortable and enjoyable for vaginal penetration.

Also, spend time yourself with the lubricants and a small dildo. Get to know how it feels on your own. A partner is fun, but learn singleplayer before joining a multiplayer game, you need to know what works because your partner can’t feel how it feels for you, it isn’t their body, they need your feedback. There is nothing wrong with enjoying your own body, it is natural and healthy and really enhances partner play as well. I guarantee you if you are with a male partner he knows a lot about what his junk needs, so it is a good idea to get that understanding for your own bits.

Other people have obviously pointed it out, but this is one of the many areas in Linux where the command line is so much easier than an interface that the people who write GUI tools just don’t bother. The tool you need for a command line approach is called dd (I imagine it stands for direct data because that is what it does). Using dd you can take data from one place and put it into another. This means you can put zeros all over a drive, wiping it in full, using

dd if=/dev/zero of=/dev/targetdevice

That will fill the whole drive with zeroes, but you could also do it with random noise first, using the below

dd if=/dev/random of=/dev/targetdevice

In the case of your ISO image there is someone who has included all the options including block size and so on, but the step you really need is to be sure you get the right device. Execuse the command below

ls /dev

Then insert your device, wait a few seconds, and run it again. You will have a list of all of the devices that were connected before and after plugging your drive in, so your drive will be the new one. It will probably show up as something like

/dev/sdc
/dev/sdc1

Notice that there are two. The first is the device, the second is the partition on the device. If you tried to put the content of an ISO image into an existing partition it would look like it had all worked but it would actually fail because the ISO is a full rip of a device, not a partition. Instead use the device itself, in this case sdc.

dd if=/path/to/image.iso of=/dev/sdc bs=4M; sync

The last bit will make your system write things to the disk and make it safe to eject it. Once that is all done it should work as a bootable USB.

It seems super complex but once you have done it a few times it becomes so easy you will regret the time spent getting a GUI installed.

If you still want a GUI you could try Gnome Disks, but I never enjoyed using it.
