What is the difference between the all-in-one vagina and the marriage hole vagina?
The marriage hole can be removed and washed easily. It is very convenient. The marriage hole is made from a very durable high elastomer material. The all-in-one type is very aesthetic. However, you cannot remove this (except for lip part of a vagina). The outer lip is very delicate. Therefore, we recommend it being well lubricated with copious water based lubricant in order to reduce friction.
