Hey there! So I say this with the utmost respect. I am 32m, with a 28f wife. We have done some swinging/threesomes in the past and something I’ve noticed after being in that community a while and talking to about a thousand people so far is that yes this can be a fun activity and build up a relationship, but that’s if it’s done perfectly. If it’s done right. These kinds of things have destroyed countless relationships when they’re done for the wrong reasons or incorrectly, or damaged friendships too. Entering these types of situations while you still have insecurities is a bad move. Those insecurities can compound into resentments over time if not addressed and cause more issues than they fix. Be wary and heed the warning. I suggest doing self-work and work on those insecurities before inviting others into a relationship. Plan things out. Usually things don’t stop at making out or flirting unless you’re at a club and can leave or something. But if you bring someone back to your place, what happens after a few minutes of making out? Things are expected to lead to more, so be sure to make it perfectly clear prior that that’s not the case. Create boundaries and discuss a dynamic prior so you both have a clear understanding of limits and boundaries. Create a safe word. In short, communicate a lot more with your partner to figure out what’s going to happen, why, what you both get out of it and where it’s expected to go after that ect.
