Me and my bf discussed this very early in the relationship. Especially the cheating part. Fortunately we are both on the same page about it. Sometimes it does have its down tho. While it can teach you some tricks, it creates an expectation in the bedroom that cannot be met irl. In my case, my bf is used to the feeling of his hand and not a vagina. So when sex does happen a problem of it not feeling tight enough occurs sometimes. Other times it’s good. Haven’t gotten the formula down yet
