Hi everyone sorry if I made some mistakes, English is not my mother language.

We're a couple in our early 30s from EU. I (M) have swinger experiences in the past. I'm straight curious and I've been a single (often as a bull) in around 5 MFM threesomes and also 1 gangbang and 1 unicorn. Since I started with my GF I stop swing but have some lust of going back.

She (F) only made a FMF with her best girl friend 10 years ago and it was more like a drunk adventure than something premeditated.

I told her about my lifestyle 6 months after we started dating. At the beginning she was shocked but appreciate my honesty.

We have 3 years of relationship now. I never push her even I let her notice that I was open to do it as a couple. Last summer she start with some curiosity but we didn't talk seriously again. This previous weekend after playing with a toy and DP, she told me she feels ready.

It was a great conversation, very open and we feel very comfortable. Unexpectedly we feel like we are more connected. The thing is, she is only afraid of broke something in our relationship. We are in a very stable point, thinking about future, marriage, kids. Even I am the one pushing to be swingers and I think we will have a bigger bond, the doubts are there. This happened to everyone, right?

She's not jealous but she says that maybe she's not ready to see me with another girl yet. As I'm the experienced one, I don't care to start doing something with a 3rd guy.

Paradoxically, she is very sexual and open, she is also a emotional person and she says that needs to be attracted to a guy not only physically, also personally. In my experiences, the best ones were when I met the couple before in a coffee or a bar and check the feeling. We probably replicate this but another advise?

As well, I tried with Twitter or Reddit but a paid website for my country it was better as the people get in only by invitation and have real verifications.

What I would like to know is in your experience, how do you recommend to start? Any books, webs, movies? I know that we need to talk about boundaries, any checklist or something? I want her to feel totally comfortable, she is my priority as I'm more open and skilled.

We don't have experiences in clubs. In my city there's a lot of options but she knows from some friends that are "dark" places and she doesn't think it's a good idea, do you think it would be very hard to start?

Thank you in advance ☺️
