I have always been attracted to females but have never explored. My bf and I of 3y  are in a relationship where it is safe to assume we will probably end up married.
 
He is a bit more experienced than me when it comes to sex in general and seems very open and ok with the idea. 

We have had our issues with "emotional cheating" on his behalf (gag, I know it sounds stupid but it's the best way to put it). I have difficulty trusting him and I'm trying to work on it, but I can't help fight this feeling of wanting to know what it's like with another girl. 

I told him we can have a 3 way but I honestly rather not include him for fear of being left out or not knowing how to handle 2 people at once.

I also worry I may lose interest in what we have. 

How can I ask him to let me sleep with someone else when I can't even completely trust him for a much less offense? Am I way out of line?

I want to have sex with a female but I can't fully trust my bf for his mistakes. I feel wrong for asking.

I'm having issues with trusting my boyfriend (and myself) with the idea of having sex with another girl. Is it a deal breaker or
