No one is going to ridicule you and the beauty about the internet is, if you choose to, that all of this can be anonymous and you can always start over. Being aroused in what you described doesn't necessarily make you a gay person, because the way you described things it feels like you're very confused about everything. You don't need other people to tell you that you are gay, bi or straight and honestly you shouldn't ponder about it too much. Just follow what feels right! Follow YOUR path of happiness, don't walk a path outlined for you. It's couragous that you're here talking about your feelings and anybody riduculing you for something that required a lot of effort and emotion is a dick! Now I don't know what your age is, but hormones sometimes screw with your mind. To the point you can question your sexuality. I'm not talking about puberty, your hormone levels scale up and down and influence your feelings a lot.
