Opening up

Me and my partner (21F & 22M) have been together for a few years now and recently just talked about adding another girl, he mentioned how he wound find it hot to see me with another girl and I think it would be hot to see him do stuff with her too. I have had threesomes before with just women but never with a long term partner..

I’m wondering how that has affected your relationship did it make it stronger and more fun? We’ve talked about our boundaries and we are pretty much open to a lot of it (and ofc would make sure the other person is aware of such boundaries). He wants me to be the one to find the girl which I really appreciate, we’ve tried the apps but I would rather it happen naturally at a bar or out somewheres.

Any advice is helpful!!
