bi-curious?😅

hi! wondering if anyone in here can kind of help me understand more about being bisexual? also what it means to be pansexual? i am a woman in a relationship with a man but for years i have been having strong urges to be with a woman. i’ve always been told by my family that i am straight and never given any options. i recently turned 18 and moved out and i would like to explore my options. i’m very nervous so any tips or comments would be appreciated! i have told my boyfriend that i want to possibly experiment with a woman and he is all for it so that’s good 😅 now i just need to work up the nerve and get some info so i don’t embarrass myself 😅
