@Hannahnim That is a good first pump to buy as it’s reasonably inexpensive. Allowing you to watch your labia and so on react to it through the clear covering so you can see and feel at the same time possibly be having or being near a mirror when you start. And start out with short intervals, just like cock rings they are not all day items so 5 then 10, 15 up to 30 minutes at a time. And if it gets painful stop
If it is something you like, there is an advanced option for when you can endure it for longer and you have a remote control dildo insert it first, pressuring the pump then turn the dildo on while in the pump
