My boyfriend (27M) of 7 years and I (26F) want to have a threesome. We've discussed this a lot over the years, and have lately been discussing it in depth. I told him recently that I've been strongly fantasizing about taking two cocks at once and he told me that the idea of it really turned him on. We're both extremely excited by the idea.

We've gone over the important stuff- boundaries, expectations, the kind of guy we'd like to include, aftercare, etc. We've watched MFM porn and masturbated together, pointing out things we'd like to try and things we'd like to stay away from. (We obviously realize porn is produced to look perfect and our experience will have a lot more awkward moments.)

I think that we have extremely solid communication when it comes to our feelings. We both go to individual therapy and are open with each other about our fears and desires.

All I see online are horror stories of threesomes gone wrong, which I understand that the people who are looking for advice are typically the only people talking about their experiences.

I'd like to hear some successful, positive threesome experiences. Any tips or things you wish you did differently welcome.
