Bicurious

I've always been super close with my girlfriends in middle school and high school being totally comfortable changing in front of them and talking to them about everything! But I've only ever dated guys. Only ever kissed guys, had sex with guys, anything. But I wish I could be close with a girl that I can also try and maybe experiment with...I have a boyfriend and we have been on the outs for a while. Idk what to do. I love my boyfriend but I can't ignore this feeling I have...help!
