I’ve been questioning my sexuality a lot lately

Does anyone else question if they’re bi but too scared to try anything with the opposite sex? I’m a 24 y/o man and have been questioning myself a lot lately. I’ve always struggled with this because I grew up super Christian (pastors kid), so homosexuality was always a preached as bad when I was growing up. I think I’ve always been a little curious, but too scared to try anything, until I did.

For most of my life I have not questioned if I was straight or not, but my curiosity usually comes in waves. A couple times in high school, once and college, and lately quite a bit. I’ve acted on my thoughts twice. Both times I experimented, after I orgasmed, I felt ashamed and have blocked it out.

I’ve gotten older and gained a willingness to try new things. Maybe I should stop blocking out the experiences I’ve already had. I have been fantasizing about trying again, but I’m nervous. What if I feel the same ashamed feeling after? I believe sexuality is a spectrum and everyone falls on a certain point, I’m just too scared to find out where I land.
