it's called kegal excercises, it's the same muscles you use when you pee.
Otherwise like I said before try dischem.
You don't need pills to get a tighter vagina, there is an exercise you keep doing and it works, many woman do it after giving birth. I forget what the exercise is called but you know when you have to go pee and you can squeeze those muscles to stop it from coming out? Well if you regularly squeeze those muscles your vagina will become tighter.Can I buy the Pill without a prescription?
