Is it normal to be extremely attracted to a teammate, sexually?

im a female, and i think about having sex a little more than i probably should. i could be chillin, or at a lecture, its weird but i am no feind, im not even sexually active! nor am i so open towards the subject with others.

well ive always had this attraction towards this girl on our volleyball team. she's really unique and pretty for a tomboy, idk her sexual orientation but making out with her passionately has been on the back of my mind for a while. it also wasnt until today i had a very provocative, very DETAILED sexual fantasy about her and i and about how fcking amazing i could make her feel. she is really, really sexy.. in a modest, respectful kind of way. idk if these thoughts are respectful lol but i really admire her.

to be honest, i dont really believe in bisexuality, no offense, i just think its one or the other, and im pretty sure im straight. would you be creeped out by this if this were you? would you be flattered? would that turn you on(If i was 'appealing' in ur opinion.. which im told often i am.. sounds conceited but being anonymous is my excuse!)?? is this normal to you? have you ever experienced anything related to this? by the way, i realize how open and immature this sounds, but its the truth! haha. comments or stories are all appreciated , thanks!
