Curious

So I have always dated boys...however my easiest turn on is a girl if I watch porn I watch girl on girl..I have always thought of myself as straight until one of my friends (bi) told me that she thinks I might be in the wrong boat and I might be bi but never tried it...always up for something new however I wouldn't want anyone to know if I was until I know 100% e.g. try it with a girl first

Any ideas/opinions ??
