Hai Michelle. I'm not you, so I can't tell you if you're transsexual.
You'll have to give more information, being transsexual isn't about desiring to be a woman you find attractive. It's not a decision that you just decide one day. Transsexuals have an intense desire to live as the opposite sex, and are generally very unhappy presenting as male. The hormones make you grow breasts, they drastically change you mentally, they drop your sex drive drastically, they eventually make you infertile, they might make you more prone to medical problems ciswomen get but I'm not sure. Just advising you. Also this sites not just for transsexuals, there's androgynes, crossdressers, significant others, etc.
Whatever you find out, welcome. ^.^
