I want to have sex with someone else

Alicia

So me and my bf have been dating for 9 years faithfully. Recently I’ve been thinking about what its like to have sex with someone else. He’s had sex with two other people when he was around 16. I’m 25 and he’s 27. I do love him, I just want to know what it would be like.

Anyone else had this situation? What did you discuss with your significant other? Is that bad that I’ve been fantasizing about it? I have not disclosed it to him yet.
