@Nurse_Nettie I don’t have any experience with this scenario however I do have some knowledge with biochem so i am going to second what nurse nettie said, that its important to use lube that is purpose made for being applied to the body and especially genitals as those lubes are precisely worked out to cause as little irritation and or be compatible with condoms and that particular area of the body. Often you will find issues down the track that make you go “Ohhhh so that’s why you shouldn’t use xyz” so it’s often best to stick to a product off the shelf made for it. I wouldn’t take any chances.
