for some reason im getting this feeling... what is it?....

So for some reason ive been thinking about girls..like my bf and i are on and off all the time, i dont know if im just in need of a best friend ( i legit only talk to my bf and he doesnt understand shit) or if im having feelings of dating a girl? I watch lesbian porn all the time, ive eaten out a girl and i thought that was fun, i dont know what im feeling ans its really scaring me. Am i bi? Or am i just lonely or something? Please help me....
