I don't care how close you are. Your friends don't need to know about your partners junk. This includes d**k pics and any other naughty selfies. Your partner took those for you and only you. Or at least let's hope so.
Sure, you can share little spicy tidbits to your friends about your sex life, but they don't need to know everything and they probably don't want to know everything. They only want to know the Cliff Notes version, so spare them all the juicy details.
If your partner confides in you, keep it between the two of you. How would you like it if they spilled the beans on all your deepest, darkest secrets to their buddies? They need to be able to trust you. Don't lose that trust by blabbing.
You call him "monkey", "monster" and "boo bear". He calls you "his little potato chip." You think that it's the cutest name, but your friends won't think so. They will think it's gross. Keep "boo boo boo bear" to yourself.
Your boyfriend drinks coffee while he is on the toilet. He then tells you all the details of how it went in there. Sometimes you sit by the door and talk to her while she poops and you also love to leave her little notes when she is in there. Totally normal, right? Nope. So let it be your dirty little secret.
Look, some people get freaky in the sheets. They may want to go wild and go to sex clubs or have a threesome here and there. It's your life so do what you are both comfortable with. As long as you and your partner or partners are on the same page, do what you want and you don't need to tell anyone what you like to do behind close doors.
He loves to pluck his nose hairs while you pop your zits in the mirror. You like to tweeze his back hairs and he likes to pick your nose. Yea it's gross, but it's your weird couple behavior and no one is going to judge you just as long as you don't tell anyone about it. If you tell anyone about it, they are going to judge you.
If you get into it with your friends and tell them every single time you guys fight, good luck to you. They will only hear your side and wind up hating your partner. Save the stories and only tell them what you absolutely need to.
Your friends don't want to hear how amazing your partner is every five seconds. It's annoying if they are single and it's annoying if they are in a relationship. It's just annoying. Try to keep it cool and keep the gushing at a minimum. No one wants to hear you brag about your other half 24/7.
If your partner is having medical issues, that is there problem and their problem only. They will share what they want to share. It is not your job to share the details of their life to anyone. Get permission before you talk.
Money is a big issue and people handle their money issues differently. Your partner would be really upset if they knew that you were talking about their financial business behind their back. Get on the same page and know what they are comfortable with before you go there.
If they cheat and you decide to leave, tell your friends anything you want. If they cheat and you stay, you better keep your mouth shut. If you want to keep the peace and if you want your friends to like the person you are dating, then don't say anything at all.
If there are things that you are keeping from your partner, you don't need to tell your friends. This includes things that bother you about them. Things that they do that drive you crazy. Things like the sex isn't good anymore, you hate their hair, you can't stand their mother. What is the point of telling anyone if you can't say these things to their face? It's mean to share so don't do it.
Let's say you are dating someone who thinks your friends are annoying. First of all, they shouldn't tell you that. But if they do, don't tell your friends how your partner feels. You will never be able to dig yourself and your partner out of that hole if you do.
If your partner is really insecure about something, don't tell people about it. Try to help them through it instead. That is something deep and personal and it isn't your business to talk to anyone about it. Talk to your friends about your insecurities and keep your partner's issues out of your mouth.
