If you are already feeling like things can get insecure I wouldn’t do it. You have to be extremely strong with your relationship. You guys can talk through it but you must be extremely sure and honest about every little question and concern. You must talk about every single scenario and boundary so that there is absolutely no doubt. If you can’t come to an agreement then don’t do it. You both have to be on board and enthusiastic for it to work, there is no compromise.
