Have no idea who this person is as I am alumi. However, to correct an annoying misconception...
Women who have sex often whether with one person or many may not loosen. If the vaginal muscles are used appropriately during coitus then this will result in exercise which will make them stronger. They will be able to contract more hence making it tighter, rather than looser. If you are going to use euphanisms please do you research. I find the inaccuracy highly offensive.
Fair play you are a bellend for writing that
