Me (m23) gf (24) have been together 6 years and about two years ago I proposed the idea of her sleeping with other guys. She didn't really think I was genuine and thought it was a way I could then sleep with other girls. Through a lot of talks and dirty talk in bed I've opened up how it's about her pleasure and my kink of her getting off to something new she might desire to experience (she's only been with two guys including me). Over these years she's made out with another older guy infront of me after a night out, taking him to the room but went no further. And another time after a night out got my mate to take us home and offered him to come inside and smoke with us, she was giving off vibes and undressed and hoped in bed with him to "cuddle" while they waited for me, we ended up both fingering her while she swapped between kissing us, unfortunately the alcohol got the best of us and we went to sleep. She now doesn't seem to want to take the plunge, there is a guy she is interested in and I've given her every green light you could but unsure how to go forward without being a pest
