I think I’m bi or lesbian

Hello I new to this app and people on here give good advice so I need some help

I have dated only men and once I had threesome with a guy I loved and want to marry but at the same time another girl was there too during it and the problem is that I love men but I always check girls out watching girl on girl porn and during our threesome she ate my pussy and I loved it and I’m also scared to touch a penis when I’m next to one and I loved seeing pussy I don’t know what that means? I’m not sure what to do

I want to also trying being intimate with a girl badly but I don’t know where I would go to find someone or tell my parents either?

Any advice please comment below and help me out!!!
