Questioning if I'm gay - nsfw

I'm in my late 20s, I've always questioned if I was gay even though I'm also attracted to women. I almost exclusively watch gay porn and love playing with toys and find some men very attractive. But the other day I finally made the leap to meet up with a guy. He wanted me to top him. He blew me for 15 minutes but I just couldn't get it up. I pretty much never have this problem and I was sober so there was no whiskey dick. It felt really good but for whatever reason I just could not get hard. He eventually left and that was that.Maybe I need to try just bottoming. But I'm really questioning my sexuality and maybe I'm not gay??? Has anyone else found themselves in this situation before?
