I'm a girl and yesterday I was sleeping over at my friend's house. We were going into the hot tub together and we were in bathing suits. She put on a one piece and when I asked why she was wearing her swim team bathing suit she said something insecure about her body. Being a good friend, I told her she was beautiful and there was nothing wrong with her. I went around a corner in her room to change into one of her bikinis and I'm not sure if it was an accident or not but she saw me changing but instead of turning around or leaving, she just stood there staring for a while. The bikini was a bit too small for me in the top and I was coming out a little. I asked for a bigger one but she said it looked fine. We got in the hot tub and put some bubbles in. She had kind of been staring at my boobs ever since she "accidentally" saw them and they were showing a bit. I tried to put a couple extra bubbles around me but then she started a splash fight and popped them all. Then she was next to me in the hot tub and she kinda pressed up against me and put her hand on my leg casually and then started moving it up. I let her do it a little but when she got up to the edge of my suit I shifted uncomfortably and she started laughing like it was a joke but I'm not sure it was. I kinda feel bad about this though because a couple times last year at parties for a joke I made out with her and we kinda felt around a little. I'm totally straight but I feel like since I was a little tipsy I went gone too far and made her think I'm interested. We're really close and we've held hands and we peck goodbye sometimes but I thought it was all innocent. Earlier that night we were on a swing and I laid down and she put my head in her lap and stroked my hair and my mouth a little then started moving towards my boobs before someone came. We've seen each other naked several times. We've even joked around (or at least I thought) about doing "stuff" or having a threesome with her boyfriend. Do you think she's attracted to me, bi-curious, or it was really just a joke? I don't want to hurt her but I don't like her like that...what should I do? We're 16.
