In response to my posts on reconnecting with your partner, one of my friends suggested the option of "trying a threesome." I think a threesome might not make sense if the ultimate goal is to get closer with your significant other, but I appreciate that there are different strokes for different folks (pun intended). A few thoughts, for what they're worth:
1. For a straight couple, a threesome tends to be a fantasy for the guy and not the girl. If your girl is bisexual or truly comfortable with exploring her sexuality, then bringing another woman into the bedroom might be a fun activity to raise the sexual bar in your relationship. But, I would do a lot of communication before to ensure that there aren't a slew of problems afterward.
Is your girl really as into this as you are? Make sure that she is not just doing this to please you, and let her know that you will not leave her or cheat on her if she doesn't feel comfortable with having a threesome.
If she is genuinely open to this, what are her ground rules? Be specific. What can you do to the other woman? What can the other woman do to her? If any participant wants to stop, what is the "out" word or phrase? ("I don't feel comfortable with this" should get the point across, but it's okay to use a code word if that makes you feel better.) Will the other two people respect the third person's wishes and walk out of the bedroom?
Is it better to pull in a female friend of hers or someone that neither of you know? That's very couple specific. If you have a threesome with someone you are close to, there are pros and cons. On the one hand, everyone might feel more inclined to relax around each other because of the shared history. On the other, you all might feel more awkward or nervous since you know this girl — either at the time or after the fact.
If you ask someone you don't know that well to join you in a threesome, how or where will you meet such a willing participant? Can you trust that she will respect the ground rules? Will you ask her about her health history beforehand or not? Will all of you feel relaxed enough around each other?
Where will this go down? Is a hotel more discreet than your home? Is it better not to have this happen in the bedroom you share with your partner? Or, do you prefer to have home field advantage?
2. Conduct a cost/benefit analysis in advance! I recommend talking with your partner beforehand about the goals of this evening. Are there other, better ways to reconnect with each other? Could you go to a strip club together and then go back to your bedroom? Bring a porno movie or toy into the mix? Take a class together with a sex educator? Go to a resort for couples? Are there other fantasies that you both have that could be fulfilled?
My concern with a threesome is that once you go there, you can't unring that bell. If it doesn't work for any reason at all, what will happen to your relationship? Is it worth losing your partner?
So, the moral of this post: proceed with caution! I'm not saying that a threesome isn't a way to reconnect with your partner, but I would make sure that the benefits clearly outweigh the risks and that everyone is on the same page!
