Having second thoughts
I can't believe I am writing this but I am chickening out. It took 3 years to tell my girlfriend (now my wife) my fantasy, 1 year of her warming up to it, 2 years of roleplaying and now we are finally exploring a third. I didn't talk to anybody yet but she gave me the green light to choose a third to introduce to our bed for an experimental threesome (we discussed to do oral only for a first encounter but its a barrier that can come off if we all feel comfortable) and I cant just bring myself to do that. She said I have the green light to choose whoever I see fit. But I cant bring myself to make a choice. Every time I see a picture of a third and his cock, I imagine his hands on my wife, his cock in her mouth. My petite innocent wife with a body count of 2 (she slept only with a high school sweetheart prior to me) will try another cock in front of me.
Now, the fantasy very much turns me on, It was my fantasy from even before meeting her, to share my partner with another man. But now that its becoming real, I feel like I am chickening out. Any advice for me?
