1. It's called a FWB for a reason
First, a FWB relationship is based on friends. You are not only having sex, but also having friendship and benefits. You and he deserve respect and honesty. My friends will tell me that their FWB will do something terrible to them. Then they will justify their actions and say, "We don't have a date, so I think it's okay." No, it's relevant. If she were just your friend, would she treat you like that? The answer, of course, is No. If a friend sticks his penis on your ass, there's no doubt that it's bad.
2. There are differences between FWB and NSA
This really needs to be repeated, because I can't tell you how many times my friends confuse the two. The NSA relationship is purely sexual. Get in and out of your apartment in 20 minutes. During that time, you said no more than 100 words, and you both reached a climax. FWB is a casual encounters relationship that requires more work and communication.
3. Give him your expectations in advance
In a FWB relationship, you need to know in advance what you expect of him. Do you want to send text messages regularly? Do you want to date him, or do you want to talk business directly? Are you talking about the other people you date? Do you want to see him once a month or when both of you are free? You don't have to sit him down and ask all these questions at once (which will scare him away), but after a few conversations, I think it's fair to ask, "Hey, what are you looking for here?" I'm sure we're on the same page, but I just want to make sure.
4. Tell her what you can give her
Two sides of the same coin. Be straightforward about what you want and what you want to give him. It's not only important to meet your needs, but also his needs.
5. Choose the right friends
Not everyone can cope with FWB. In fact, I don't think most men can. Choose a suitable friend to explore an FWB relationship, because he knows there is a possibility that the relationship will break out. Don't choose your best friend, because if something goes wrong, you may lose him. Similarly, don't pick someone who works in a cubicle next to you because you see his butt every day. Do you always like a good friend who lives in a neighborhood but doesn't want to date? Now it sounds like an ideal choice, right there!
