Venting..Maybe could use some advice.

Hey Everyone. i’m 17 and have been dating my boyfriend for 2 years. lately, maybe for the past couple weeks, i’ve been thinking about, like, being bi? and its so conflicting. i want to say that it’s a phase, but i know that sexuality is not a phase. i’m not romantically attracted to women, but i might be attracted to them sexually. i’m romantically and sexually attracted to men. i haven’t mentioned any of this to my boyfriend and i don’t think he’d have that much of a problem with it if i was actually bi. i know my parents wouldn’t be happy about it, but because i’m not romantically attracted to girls i don’t think i would ever share it with them. i’ve always considered experimenting with girls, but i’ve always been so nervous about it because i think that putting myself out there with people i know would be scary and i don’t want people to get the “wrong idea” about me. can someone maybe explain what i might be feeling? please be kind!
