<human>: I have been dating my girlfriend for three years this Thursday. I love her to death and she loves. She knows I am bi-curious and doesn't care that I watch gay porn nor and is totally supportive of who I am. The only problem is I feel like I would really like to try being with a man sexually (I don't actually find men attractive/ nor would I want to be in a relationship with one). 

She does not like the idea which is completely understandable and I would never cheat on her. But this leaves me at a cross-roads. Do I leave a potential future wife or risk living with regret for the rest of my life. Has anyone had experience with this?

<bot>: Want to try sex with dudes, girlfriend isn't okay with it. I love her but I also don't want to live a life with regrets.
