Hi my sweet ! I am so happy to give you new knowledge and today is no exception ! ๐โโฌ๐ IS LUBRICANT NECESSARY ?๐ฅ๐ฅต The amount of natural lubrication depends on the medication a girl takes and how much fluid she drinks per day. But natural lubrication is only enough for 15 minutes, so the longer couples want to have sex, the more lubricant should be used to avoid friction and discomfort.
