Having a threesome was my biggest fantasy – but I fear it’s ruined my relationship

DEAR DEIDRE: HAVING a threesome was always my biggest fantasy, but now I fear it’s ruined my sex life.

I’m a man of 28 and my girlfriend is 25. We’ve been together for two years and I thought we had something special.

I had always dreamed of having a threesome. I had mentioned it to my partner casually but she never seemed interested.

Then out of nowhere she told me she was open to giving it a go.

I was taken aback at first but also excited by the prospect.
