I Will try to make ir quickly, English is not my main language. So I have been 19 months with my gf, not gonna go to deep in this but sexual life is pretty pretty good, we both have though about threesomes before, with both men and woman, but she is more into woman than men, here is my problem. She has always though that i am 100% heterosexual, completely and I always says yes to that bc I didn't know how to talk about that, but, I AM bisexual, she is pan, I want to know how to tell her that I want a threesome we're I make out with the other man too, she does not know that I want that dynamic in a threesome and I don't know how to tell her that I am bisexual and want that kind of dynamic. She has told me before that she wants to see me with another woman and she wants me to see her with another man, I have rejected both things bc I want the 3 to participate. But I don't know how to tell her everything . Help and sorry for the Bad English
