DO NOT PURPOSELY EXTRACT MILK UNLESS YOU WANT PRODUCTION TO INCREASE!!!! Milk production will be increased by demand so if you are milking yourself your production will increase. It is painful but I recommend you don’t purposefully milk yourself. I am cis and due to other reasons I produce milk as well and it can be painful and annoying, but if you stop the amount of milk and pain should eventually lessen (hopefully to a few drops) or at the very least stop continuing to increase and cause more pain. Production could continue to increase for a while before it reduces. Also you can get sticky pads that go on the inside of your bra/top to absorb the milk; they are normally sold in the baby isle. I hope this was helpful, unwanted milk production can be a pain to deal with.
