Considering an MMF with my wife, but wondering if our reasoning makes sense
My wife and I are early 60s, together 40 years, very solid sexual relationship.
We haven't been able to have PIV sex in a very long time, but we're still sexually active 5+ times a week in other ways.
A few months ago I realized I'm bisexual and told her. She was very supportive.
Last week she suggested a MMF threesome. I could explore being with a man, and she could have PIV again, which is something she really misses.
She doesn't have anyone in mind. This is a general idea, not something driven by a specific person.
I'm into the idea. I'm especially curious about being with a man, and I also like the idea of her getting something she's been missing for a long time.
The only mixed feeling I have is that while I'm turned on by the idea of seeing her with another man and even participating in 3-person acts, there's also a small part of me that feels a little sad that it's someone else's P in her V. I don't think it would hurt our relationship, but it's there.
For me, getting off with her in other ways feels just as good as PIV, but I know for her it's a completely different feeling, and she misses it.
We communicate well and have talked about all this openly. Neither of us is worried about this turning into something emotional or ongoing with another person. That's not something either of us is looking for.
We would be going into this with our eyes open. We understand that some men may present themselves as bisexual just to get access to sex with my wife, and we've already talked through how we'd recognize that and address it if it came up.
We've also discussed boundaries and expectations ahead of time. Nothing so rigid that it would kill the spontaneity, but enough that we both feel comfortable, know what's on the table, and have a clear way to pause or stop if either of us, or the third, needs to.
I think what I'm really trying to understand is whether this mix of excitement and a bit of emotional hesitation is something normal to work through, or a sign we should slow down. I'm also wondering if our reasons for this might be a red flag in themselves.
Is having an MMF threesome a mistake for us?
