I think I'm bisexual and want to experiment

Always been strictly straight, until recently. I've been masturbating to gay porn a lot, and find the thought of giving oral to another guy, and getting it from a guy, extremely hot. When I watch straight porn I fantasize about being the girl often, and being very sultry, makes me rock-hard and have amazing orgasms. Also have been flirting with guys and it's been really making me horny, and I find I'm attracted to many guys.I have a bisexual friend of mine, and was considering asking him about it and seeing if he wanted to experiment, and try things out with me. I would only feel safe doing things like that with someone I personally know. I know he's very open with his sexuality. Very, very nervous about this. Any advice would be welcome.
